Description

The STEVAL-ISA082V1, based on the

ST1S40IPHR, is an internally compensated

800 kHz fixed-frequency PWM synchronous step-

down converter demonstration board.

The ST1S40 operates from 4.0 V to 18.0 V input,

while it regulates an output voltage as low as

0.8 V and up to V

The ST1S40 integrates a 95 mΩ high-side switch

and a 69 mΩ synchronous rectifier allowing very

high efficiency with very low output voltage.

The peak current mode control with internal

compensation delivers a very compact solution

with a minimum component count.

The ST1S40 is protected through cycle-by-cycle

current limiting in case of overload and is also

protected by a current foldback function with

frequency reduction in case of short-circuit.

The device is available with an enable on/off

function.
