3 Description

The TPSM82830x are an easy-to-use, synchronous,

step-down, DC/DC module family with integrated

inductor and EMI reduction technologies. Based on

the DCS-Control topology, the devices have a fast

transient response yet 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 prolongs battery life

at low output currents and the forced PWM mode

maintains continuous conduction in the inductor

to reduce ripple at constant switching frequency.

An internal soft-start circuit ramps the voltage up

tightly controlled and a power-good signal indicates

correct output voltage. The devices support 100%

mode. HICCUP short-circuit protection combined with

thermal shutdown protect device and application. The

family is available in a 3.0mm × 3.0mm × 1.95mm

QFN package and 2.5mm × 2.6mm × 1.95mm

MagPack package.
