Description
The STEVAL-ISA068V1 is based on the ST1S32,
an internally compensated 1.5 MHz fixed-
frequency PWM synchronous step-down
regulator.
This device operates from 2.8 V to 5.5 V input,
while it regulates an output voltage as low as
0.8 V and up to V_in.
The peak current mode control with internal
compensation delivers a very compact solution
with a minimum component count.
