open-in-new Find other Buck modules (integrated inductor)

Description

The TPS82084/5 are 2-A/3-A step-down converter MicroSiP™ modules 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 startup reduces the inrush current required from the input supply. Over temperature protection and Hiccup short circuit protection deliver a robust and reliable solution.
