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.
