Compact 3A step-down converter offers high efficiency

This post is sponsored by Texas Instruments. The TPS82085 from Texas Instruments (TI) is a 3A step-down converter MicroSiP module optimized for small solution size and high efficiency. The power module integrates 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 2.4MHz and automatically enters Power Save Mode operation at light load currents. In Power Save Mode, the device operates with typically 17-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 start-up reduces the inrush current required from the input supply. Over-temperature protection and Hiccup short-circuit protection help to deliver a robust and reliable solution.
