The TPS82085 device is a 3-A 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 startup reduces the
inrush current required from the input supply. Over temperature protection and Hiccup short circuit
protection deliver a robust and reliable solution.
