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 soft-start circuit reduces inrush current and a power-good signal indicates correct output voltage. HICCUP short-circuit 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.
