Description

PMP20396 is a multiple-output isolated bias supply reference design. With 100V or above input voltage, this design can provide maximum 2W output power. With 300V or above input voltage, this design can provide maximum 50W output power. Four different outputs are provided in this design - 5V/500mA and 12V/50mA at primary side and 5V/700mA and 12V/4000mA at secondary side. Peak 90% efficiency is achieved in this design.

Features

  • 2W maximum output power with 100V or 400V input
  • 50W maximum output power with 300V to 400V input
  • 90% peak efficiency
  • Multiple-output - 5V/500mA, 12V/50mA at primary, 5V/700mA, 12V/4000mA at secondary

Typical applications

  • USB-Compliant Adapters and Chargers for Consumer Electronics / White Goods
  • Standby Supply for TV and Desktop
