Product overview

Description

The STEVAL-ISA160V1 evaluation board is based on the AST1S31HF internally compensated 2.3 MHz fixed-frequency PWM synchronous step-down regulator.

The device operates on a 2.8 V to 4.0 V input voltage and provides a regulated output voltage from as low as 0.8 V up to Vin.

The peak current mode control with internal compensation delivers a very compact solution with a minimum component count.

All the components on the evaluation board are automotive grade.
