Description

The STEVAL-ISA084V1, based on the ST1S40, is

an internally compensated 800 kHz fixed-

frequency PWM synchronous step-down

converter demonstration board.

The ST1S40 operates from 4.0 V to 18 V input,

while it regulates an output voltage as low as 0.8

V and up to V

The ST1S40 integrates 95 mΩ high side switch

and 69 mΩ synchronous rectifier allowing very

high efficiency with very low output voltages.

The peak current mode control with internal

compensation delivers a very compact solution

with a minimum component count.

The device is protected through cycle-by-cycle

current limiting in case of overload and is also

protected by current foldback function with

frequency reduction in case of short-circuit

The device is available with an enable on/off

function.
