3 Description

The TPSM82830x are a family of 1A, 2A, and

3A, pin-to-pin compatible, easy-to-use, synchronous,

step-down, DC/DC modules with integrated inductor

and EMI reduction technologies. The devices use

DCS-Control topology for fast transient response with

small output capacitance. The output voltage can be

set down to 0.5V with high feedback voltage accuracy

of 1% over the full operating junction temperature

range. A mode pin selects between power saving

and forced-PWM mode. The power save mode is for

longer battery life and the forced PWM mode reduces

ripple with continuous conduction in the inductor at

a quasi fixed switching frequency. An internal softstart

circuit reduces inrush current and a power-good

signal indicates correct output voltage. HICCUP shortcircuit

protection combined with thermal shutdown

protect device and application. The family is available

in a 3.0mm × 3.0mm QFN package and in the

2.5mm × 2.6mm MagPack package.
