Buck-Boost Evaluation Board User Guide
Introduction
The PI3740-00 evaluation board comes in two versions, EVAL1 and EVAL2. EVAL1 should be used to
evaluate the PI3740 in constant voltage or standard constant current applications where V
OUT
is above
8V. EVAL2 is designed for specialized constant current applications using high-side current sense where
V
OUT
is below 8V. These boards have been designed to showcase various constant voltage and constant
current applications and can be configured with a few selectable jumpers. This guide will walk the user
through the various options.
The PI3740-00-LGIZ is a high efficiency, wide input range DC-DC ZVS Buck-Boost regulator with
integrated controller, power switches, and support components all within a high density
0.4” x 0.55” System-in-Package (SiP). The evaluation board measures 2.5”x2.25” and contains all
the components necessary for a variety of applications. Not all components will be needed for
all applications.

IMPORTANT NOTICE:
Be sure to read the precautions below entirely BEFORE using the evaluation board. Do not operate the
evaluation board unless you have the appropriate safety precautions in place on your bench to ensure a
successful experience.
The list below is not comprehensive and is not a substitute for common sense and good practice.
When testing electronic products always use approved safety glasses. Follow good laboratory practice
and procedures.
During operation, insure the power devices and surrounding structures can be operated safely.
Care should be taken to protect the user from accidental contact when under power.
Provide a strain relief for wires and place the system on the bench in such a way as to prevent
accidental displacement from bench top.
Review thermal consideration and guideline associated with operating the evaluation board. Most
notably use a bench top fan and use rubber feet to elevate the PCB as they allow air flow
to the bottom.
Remove power and use caution when connecting and disconnecting test probes and interface lines
to avoid inadvertent short circuits and contact with hot surfaces.
Verify power connections to avoid reversing applied voltage polarities.
Avoid creating ground loops between the SGND and PGND pins when making measurements.
The product evaluation board is designed for general laboratory evaluation. It is not recommended
for installation in end user equipment.
Refer to the specific regulator module data sheet for electrical rating of the device, thermal and
mechanical product details. It is important to remain within the device rated range when testing.
The evaluation board is designed for user convenience to evaluate the performance of Vicors mounted
ZVS Buck-Boost product. Sockets are provided to permit quick probing. The evaluation board provides
lugs and top layer banana jack footprint for input and output connections, signal connectors allowing
wire, signal test points for easy connection to standard test equipment, and Kelvin Johnson-Jack for
accurate voltage measurements of power nodes.

Constant Voltage Operation (EVAL1)
For constant voltage operation install JLGH, JPG, JISP, JISN as shown in Figure 1. The regulated output
voltage can be adjusted by changing REA1 per the following equation.
V
FLOAT
= (1.5887*REA1) + 1.7 where REA1 is in kΩ. With the present values, the output
voltage is about 24V.
Note: During constant voltage operation, short VSP to VDR to ensure the PI3740 internal amplifier does not affect
performance.
Constant Current Operation (EVAL1, EVAL2)
Constant Current mode is required for battery and super capacitor charging applications. Both EVAL1
and EVAL2 can be configured for constant current operation. EVAL1 should be the default board for
all constant current applications with the exception of high side current sense applications where V
OUT
can drop below 8V. Both evaluation boards can be configured to operate in a typical CC/CV charging
scheme where the regulator output starts out in CC mode and then transitions to CV mode as soon as
the battery voltage reached a predetermined float voltage.
Constant Current Float Voltage Adjustment
The float voltage or the voltage where the converter transitions to constant voltage mode, can be
adjusted by changing REA1 per the following equation.
Vfloat = (1.5887*REA1) + 1.7 where REA1 is in kΩ. The board is shipped with REA1 = 14kΩ which
sets the float voltage to 24V. The board is also shipped for easy configuration for V
OUT
values
of 48V and 12V.
To configure for one of these preset values simply remove REA1 and place a jumper on J302 for 48V
OUT
or J303 for 12V
OUT
.

Constant Current Configuration #1: (PI3740-00-EVAL1 Board)
Low Side Current Sense Using PI3740 Internal Amplifier
This configuration senses the current through R106 and uses the internal general purpose amplifier of
the PI3740 to regulate the current. The jumpers need to be installed as shown. This configuration can
be used for super-cap charging as well as battery charging. The benefit of this configuration is that you
can use a standard value current sense resistor and adjust the current by changing a single 0603 resistor.
It does require 6 resistors and a reference to implement the circuit. These components are contained
within the evaluation board.
Install: JSHUNT, JVSN, JVSP, JLGH, JGP. Also install JISP & JISN between the 2 pins closest to JGP. This
will short IS+ and IS- to ground.
Adjusting the Charging Current
The charging current can be adjusted by changing R104 per the following equation.
Icharge= (0.62-(62µA*R104))/R106. In this example it would be: (0.62-(62µA*5.11k)/0.1 or 3.03A

Constant Current Configuration #2: (PI3740-00-EVAL1 Board)
High Side Current Sense Using R
SENSE
For customers who prefer high-side current sense, this configuration senses the current through R
SENSE
and uses the internal Imon amplifier and the LGH pin of the PI3740. The LGH pin is the inverting
input to an amplifier which has a 0.1V reference. Including R
SENSE
, only 4 components are required
for the current control loop. V
OUT
minimum is 8V due to the common mode range of the IMON
amplifier. This configuration cannot be used for super cap charging.
Install jumpers as shown.
Install: JISP, JISN connecting RSENSE to IS+ and IS-, J200 connecting IMON to LGH, JTRK.
Charging Current: The LGH amplifier has a reference of 100mv nominally. The Imon amplifier has a
gain of 20. So the voltage across R
SENSE
will be 5mv when the circuit is active. Therefore, the current will
be approximately 5mv/R
SENSE
.

Constant Current Configuration #3: (PI3740-00-EVAL1 Board)
Low Side Current Sense and LGH
Current is sensed through R106 and, through a compensation network, fed into the LGH pin. This
is a low-side current sense configuration which requires only 4 components including the current
sense resistor.
Install jumpers as shown.
Install: J200 connecting R106 to R205/R206, JTRK, JISP and JISN shorting IS+ and IS- to ground.
Charging Current: The charging current will be approximately 100mv/R106. If a standard resistor value
cannot be found that gives you the required current, use configuration #1.

Constant Current Configuration #4: (PI3740-00-EVAL2 Board)
High Side Current Sense Using INA193 and LGH
For applications where V
OUT
is below 8V and high side current sense is preferred, this
configuration must be used. This configuration senses current through R
SENSE
and the output of the
INA193 is fed into the LGH pin through a compensation network. The minimum recommended R
SENSE
is
20mΩ. The maximum output voltage in this configuration remains 50V
DC
.
Install jumpers as shown.
Install: J301, JTRK, JISP and JISN to connect IS+ and IS- to ground.
Charging Current: The INA193 has a gain of 20. The output of the INA193 is divided down by R301
and R302. The LGH voltage is 100mv. Therefore the charge current is approximately
(100mv*8/20)/R
SENSE
, or 40mv/R
SENSE
.
Paralleling Boards
Current Sense Element in Each Board
If more current is required than can be supplied by one board, two boards may be used in parallel.
Jumper the following pins together between boards; SGND, TRK, EAO, EN. Use short, low impedance
jumpers especially on the SGND and EAO pins.
Only One Current Sense Element
If only one board has a current-sense resistor, the LGH pins must also be connected together. Also,
the connection to IMON, on the board which does not have the current-sense resistor, must be
opened. (Remove J200).
Stability
The both evaluation boards are designed to be stable in a wide variety of applications. If instability is
seen in your application, contact Vicor’s application support for assistance.
