Texas Instruments TPSM8282x/TPSM8282xA 1A/2A/3A Buck Converter Power Modules are converters in a MicroSiP™ power module optimized for small solution size and high efficiency. The TI power modules integrate a synchronous step-down converter and an inductor to simplify design, reduce external components, and save the PCB area. The low profile and compact solution are suitable for automated assembly by standard surface mount equipment. To maximize efficiency, the converter operates in PWM mode with a nominal switching frequency of 4MHz and automatically enters Power Save Mode operation at light load currents.
In Power Save Mode, the device operates with typically 4µA quiescent current. Using the DCS-Control topology, the device achieves excellent load transient performance and accurate output voltage regulation. The EN and PG pins, which support sequencing configurations, bring a flexible system design. An integrated soft startup reduces the inrush current required from the input supply. Over temperature protection and hiccup short circuit protection deliver a robust and reliable solution.
