Introduction
This guide explains how to use the NCL31000ASGEVB
with an USB to I2C interface or with an arduino
microcontroller board of choice to evaluate the product.
Board Connections
The NCL31000ASGEVB (Figure 1) is an arduino shield
form factor containing a single NCL31000MNITWG LED
driver. These few steps are required to get started.
1. Connect a lab power supply from 24 V to 57 V to
the DC IN connector. A reverse polarity protection
circuit is in place to protect the system against
faulty connections.
2. Connect a LED string rated for 16 V to 42 V to the
LED connector.
3. Optionally, connect an NTC from the LED module
to the TLED connector to measure the LED board
temperature. If doing so, remove R24 and short
R33, see section LED Power.
4. Connect a microcontroller to the arduino interface
connectors and develop firmware to evaluate the
product.
5. An alternative for step 4 is to use an USB to I2C
interface to send commands from the PC to
NCL31000ASGEVB.
MicroController Interface
The NCL31000 hardware requires at least a GND
connection and an I2C or SPI connection to control the main
functions of the chip. The SCL/SDA and connections are
designated to Arduino pins D15 and D14. All Nucleo boards
can be programmed to route an I2C peripheral to these pins.
The default I2C address is 0x52. This is configurable
with zeroohm resistors.
The NCL310xx devices are internally hardwired to use
either SPI or I2C. For now, NCL31000ASGEVB is only
available with the I2C version populated. Note that the SPI
slave in NCL310xx only supports Mode 2.
For Visual Light Communication, preferably a DAC
connection or alternatively 2 x PWM connections are
needed. See section Dimming and VLC YellowDot.
The DAC connection is not specified by the Arduino
hardware interface and different microcontroller boards
connect the DAC to different pins. By default,
the NCL31000ASGEVB assumes the DAC can be
connected to A2 or D13 (see Schematic). This is compatible
with the ST Nucleo boards.

DCDCs
Two DCDC supplies are available to supply different
parts of the application. VDD1 is a fixed 3.3 V supply rated
to deliver up to 150 mA and VDD2 is configurable, but on
the EVB it is set for 5 V. It can source up to 500 mA. VDD1
and VDD2 are not connected to the arduino interface so
VDD1 does not by default supply the arduino board because
the arduino interface standard does not provide a 3V3 supply
connection. Some arduino microcontroller boards can be
adjusted so that they can be supplied with 3V3. For example,
the nucleo boards normally need one or more solder bridge
configuration changes to be able to get powered from a 3V3
supply. See the VDD1_EXT connection in the schematic.
The VDD2 cannot be used to supply the microcontroller
since it has to be enabled first in a register after startup. Thus,
by default, without making any changes to the hardware, the
microcontroller board has to be supplied by the USB
connection or another supply.
LED Power
This EVB has a significant copper cooling plane for the
top fet of the LED driver. It is therefore possible to drive
LED loads up to 100 W with this EVB. 2 NTC’s are placed
onto the cooling plane to measure the plane’s temperature to
estimate the top fet junction temperature. One NTC is
connected to the TLED metrology measurement pin so that
the temperature can be monitored over I2C. The second
NTC is electrically connected on one side to the copper
plane and one side floating so that a multimeter can measure
the voltage over the NTC. This is an alternative NTC sensing
method. To measure the NTC voltage from the LED board,
make the connection to the TLED connector and solder R24
and remove R33 to disable the top fet measurement.
It is best to replace the sense resistor with 50 m or place
a second resistor in parallel to reduce the temperature of the
sense resistor and the dissipation when going above 1.6 A
LED current or so. See the Thermal section for more info.
Dimming
To make dimming possible, enable the LED driver by
setting the LED_EN bit in the CTRL register and close the
PWM_EN jumper on the EVB.
There are 5 ways to dim the LEDs. The selection for the
first three methods is made with the DIMSEL jumpers. See
Figure 2.

INTDIM
The internal 7bit DAC can be used to DIM the LEDs.
With 128 dimming steps in the entire range this method
provides a coarse method to dim the LEDs. The lowest
current value is about 10 mA if a 100 m sense resistor is
used. If deep dimming or VLC is not needed this method
may suffice. No extra hardware is needed, only the I2C or
SPI interface.
ADIM
The ADIM signal can dim the LEDs with a higher
accuracy and precision compared to the other methods. It is
possible to accurately dim down to about 0.1% of the
maximum range. The accuracy at these low dimming values
is dominated by the relative offset error, which is no more
than a few mVs or approximately 0.1% of VREF. The
precision or resolution is defined by the amount of steps the
dutycycle has in the PWM period. For example, if an 8bit
timer is used, 256 steps are available. PWM oversampling
can increase this number.
The ADIM method is an alternative to the INTDIM
method. Switching between these methods is possible by
controlling the INTDIMEN bit. To use the ADIM method,
the microcontroller must provide a PWM signal with a
frequency preferably between 1 to 10 kHz. The dutycycle
defines the dim value. This PWM signal is filtered heavily
and the resulting average value is presented to the DIM
input. The resulting LED current is thus a constant current,
not a PWMed current. This ADIM or the MDAC method
can use VLC. Next to low pass filtering the PWM signal, the
filtering circuit also couples the VLC signal on the DIM
signal. To make use of this method configure the DIMSEL
jumper for ADIM and pull the PWM pin high by closing the
PWM jumper.
PWMDIM
The PWMDIM does not provide the widest dim range or
best accuracy and should not be used as the primary dim
method, but it can be used on top of the ADIM method to
achieve hybrid dimming and dim to even lower LED
currents. For example, set ADIM to 220 mV and apply a
PWM signal of 1 kHz and 25% dutycycle to achieve an
average internal DIM voltage of:
200 mV + 0.25 * 20 mV = 205 mV
Important to note is that the measured LED current from
the ILED metrology register is not valid when using
PWMDIM. This is because the ADC sampling is in the range
of 100 ms and the PWMDIM frequency is the range of
400 Hz and higher and thus oversampling is not possible and
no averaging can be done.
MDAC
This method uses the DAC in the microcontroller, if
available. This method can dim the LEDs and still have the
possibility to use VLC. To use the DAC, route it to A2 or D13
on the Arduino interface (possible for Nucleo64 or
Nucleo144 connections) and configure DIMSEL jumper
for MDAC. When using the DAC you cannot use the
SPI_CLK and thus only I2C is an option. One exception is
the Nucleo64 boards, which connect the DAC to A2 on the
Arduino interface. Also pull the PWM pin high by closing
the PWM jumper.
ADIMP
The potmeter on the EVB can be used to apply a voltage
on the dim pin and manually control the LED current. To
make use of this method configure the DIMSEL jumper for
ADIMP and pull the PWM pin high by closing the PWM
jumper.
Status Indication
The boards have four LEDs. Two green LEDs to indicate
the 3V3 (VDD1) and 5 V (VDD2) supplies are active. Note
that VDD1 must be active on power up. This is a good check
to see if the board (supplies) is operational. VDD2 is
disabled at startup and can be enabled in a register. The
orange INTB LED is active if the INTB line is low. This is
the case when a fault bit is active or became active since the
last read. The red FAULT LED can be used by the
microcontroller.
VLC YellowDot
The YellowDot program is a luminaire certification
program that allows manufacturers to test and certify that
their LED luminaires are interoperable with Signifys indoor
positioning technology. A key aspect of YellowDot ready
LED drivers is that data can be transmitted by modulating
data onto the LED current and thus in the light output. The
NCL310xx products are Yellowdot compatible. This
means that it is possible to modulate the LED current
conform to the Yellow–dot specification. Contact Signify
for more information about this program and the technical
requirements. Modulating the data on the DIM pin can be
done either by using the MDAC (preferred) method or by
using the ADIM method together with the PWMVLC signal.
VLC with MDAC
The DAC voltage controls the DIM voltage directly.
When no data is transmitted, it should regulate a stable DC
value to provide a stable LED current. When transmitting
data, the DAC voltage swings between the 3 voltage levels
at the symbol rate.
VLC with ADIM + PWMVLC
An alternative for the DAC is to use 2 PWM signals. One
is for setting the DC dim value using the ADIM method and
the other PWM signal is connected to the PWMVLC signal.
The PWMVLC data is coupled onto the DIM signal. The
frequency must be about 200 kHz or more. A digital one is
represented by a dutycycle of 50% + k. A digital zero is
represented by a dutycycle of 50% k. The resulting signal
is a 200 kHz PWM signal for which the dutycycle varies
between 2 values (0.5 k and 0.5 + k). The symbol rate of
the VLC signal (typ: 4 kHz) is defined by the rate at which
the dutycycles alternate. The k value defines the
amplitude of the VLC signal. After filtering the resulting
EVBUM2798/D
www.onsemi.com
4
signal is a 4 kHz AC signal with a given amplitude. This
signal is capacitively coupled on the DIM signal so for this
to work the ADIM dimming method must be used to define
the DC DIM level.
Thermal
The highest temperatures on the board are to be expected
in the top fet of the LED driver and in the sense resistor of
the LED driver.
LED Sense Resistor
It is best to keep the sense resistor value as small as
possible without impacting the dynamic dimming range too
much. Keep the power dissipation in the 6430 package
below 400 mW. Ideally 200 mW. It is possible to add a sense
resistor in parallel to spread the dissipation (1% or better).
For example, a 120 m 6430 package with a 0.62 3216
package in parallel gives 100 m and a better spreading of
heat.
Thermal Plane
The power dissipation in the top fet is dominated by
switching and conduction losses. The device used on the
board is carefully selected to achieve the lowest power
dissipation. Still, mainly depending on the input voltage,
switching frequency and during highest current, the power
dissipation (Pt) can reach up to about 1.2 W in this device.
A copper cooling plane is required to transfer enough heat
to the environment to keep the temperature of the fet in 4
check. The cooling plane is about 3 x 2 cm. It is present on
3 layers: top, bottom, and one internal layer. The remaining
internal layer is reserved for a ground plane. The copper
extends to the edges of the board. The layers are
interconnected by vias. See Figure 3. The red area is the
copper plane on the top copper. This copper plane is a bit
overkill for applications that do not require 90 W or more.

Erratum
Boards with version «ncl31000as» and date
«25/03/2021» had a mistake in the arduino pinout. Headers
J6 and J7 are swapped in the layout and do not correspond
with the correct arduino placement. Modifications have
been made to these connectors so that the board can still be
plugged on top of an arduino mcu. 5 pins have been cut and 3
connections rewired.
Because of this patch the arduino shield fits an arduino
microcontroller board and it can be used as expected except
for the PWM1 pin which is not available due to this patch.
