3 Description
The TPS82150 is a 17-V input 1-A step-down
converter MicroSiP™ power module optimized for
small solution size and high efficiency. The 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 2.0
MHz and automatically enters Power Save Mode
operation at light load currents. In Power Save Mode,
the device operates with typically 20-µA quiescent
current. Using the DCS-Control™ topology, the
device achieves excellent load transient performance
and accurate output voltage regulation.
