Description for the TPSM828303
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.
