TPSM82830x Step-Down Power Modules

Texas Instruments TPSM82830x are a family of 1 A, 2 A, and 3 A, 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 to achieve a fast transient response with small output capacitance. The output voltage can be set low as 0.5 V with high feedback voltage accuracy of 1% over the full operating junction temperature range. A mode pin selects between power saving mode (PSM) and forced-PWM mode (FPWM). The power save mode is for longer battery life, and 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 3.0 mm x 3.0 mm QFN package and in the 2.5 mm x 2.6 mm MagPack™ package.
