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.
