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.
