Description

The PMP4481 reference design is designed for telecom application with a DC input of 3V~6V achieving the lowest component count. Detailed data is provided. The output voltage could be modified by resistors over the resistor divider from 0.6V to 3.3V. A typical application is for 0.9V/6A.

Features
  • Low Input and Output Voltage
  • High Efficiency 76% at 0.9Vo with 3.3Vin and 94.3% at 3.3Vo with 5Vin
  • Pre-bias soft start
  • Protection feature OCP, Input UVLO, SCP, PGood
  • High Power Density with lowest component count
  • Small dimensions: 10mmx20mmx3mm
