AMS AS1360 User guide

Brand: AMS

Model: AS1360

Type: User guide

AMS AS1360 is a 3A, step-down voltage regulator with integrated inductor that provides high efficiency with a minimal number of external components. It is ideal for applications requiring a regulated voltage from an unregulated input source, such as batteries or solar panels. The AS1360 is capable of delivering up to 3A of continuous output current with an input voltage range of 2.7V to 20V and an output voltage range of 0.8V to 12V.

The AS1360 is available in a small, 3mm x 3mm DFN package and is easy to use, requiring only a few external components. It is also highly efficient, with a typical efficiency of over 90%, making it ideal for battery-powered applications.

4 Getting Started

This AS1360 Evalboard comes with the AS1360-33 soldered on.

The Evalboard is designed to work with all available AS1360 output voltage versions.

If not present get the datasheet for the AS1360 from www.austriamicrosystems.com. Drive the IC on the evaluation

board only with the recommended settings and values as described in the datasheet.

Connect a supply voltage of up to 20V to Vin “A” and GND “B”.

If there are questions do not hesitate to contact us. See contact information at the end of the application note.
