TPSM82823 – 5.5V input, 3-A step-down module with integrated inductor in tiny package

The TPSM8282x device family consists of a 1-A, 2-A, and 3-A step-down converter MicroSiP™ power modules optimized for small solution size and high efficiency.

The power modules integrate a synchronous step-down converter and an inductor to simplify design, reduce external components and save PCB area. The low-profile and compact solution is 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 a typically 4-µA 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.
