STEVAL-ISA047V2

1.5 A / 3.3 V step-down DC-DC converter

demonstration board based on the ST1S03A

Features

■ Step-down current mode PWM (1.5 MHz)

DC-DC converter

■ 2% DC output voltage tolerance

■ Internal soft-start for start-up current limitation

and power on delay of 50-100 µs

■ Typical efficiency: > 85%

■ Inhibit function

■ 1.5 A output current capability

■ Not switching quiescent current: max 1.5 mA

(overtemperature range)

■ Switch VDS: max 200 mV @ ISW = 750 mA

■ Uses tiny capacitors and inductors

■ RoHS compliant

Description

This demonstration board is based on the

ST1S03A, an adjustable current mode PWM

step-down DC-DC converter with internal 1.5 A

power switch, packaged in a 6-lead DFN 3x3 mm.

It's a complete 1.5 A switching regulator with its

internal compensation eliminating additional

component.

The constant frequency, current mode, PWM

architecture and stable operation with ceramic

capacitors results in low, predictable output ripple.

However, in order to maximize the power

conversion efficiency with light load, the regulator

reduces automatically the switching frequency

when the output load becomes less than 250 mA

typically.
