PM8903TR - 3A step-down monolithic switching regulator

Download the PM8903TR datasheet PDF. This datasheet also covers the PM8903 variant, as both devices belong to the same 3a step-down monolithic switching regulator family and are provided as variant models within a single manufacturer datasheet.

Description

The PM8903 is a high efficiency monolithic stepdown switching regulator designed to deliver up to 3 A continuous current.

The IC operates from 2.8 V to 6 V input voltage (VIN).

Features

  • Integrated 35 mΩ MOSFETs for high efficiency.
  • 3 A continuous output current.
  • 2.8 V to 6 V input voltage (VIN).
  • 2.9 V to 5.5 V supply voltage (VCC).
  • Adjustable output voltage down to 0.6 V.
  • 1% output voltage accuracy.
  • 1.1 MHz switching frequency operation.
  • PSKIP mode to optimize light load efficiency.
  • Embedded bootstrap diode.
  • Thermally compensated loss-less current sense across HS and LS MOSFETs.
  • OV/UV/OC and overtemperature protection.
