PTB48520W - 48-V INPUT ISOLATED DC/DC CONVERTER

General Description

The PTB48520W is a 25-A rated, 48-V input isolated dc/dc converter that incorporates Auto-Track™ power-up sequencing.

This allows these modules to simultaneously power up with any other downstream non-isolated, Auto-Track compliant module.

Key Features

  • Input Voltage: 36 V to 75 V.
  • 25-A Total Output Current.
  • 91% Efficiency.
  • Wide-Adjust Output Voltage: 1.8 V to 3.6 V.
  • Overcurrent Protection.
  • Output Overvoltage Protection.
  • Overtemperature Shutdown.
  • Output Enable Control.
  • Auto-Track Compatible Sequenced Output.
  • Smart-Sense Remote Sensing.
  • Undervoltage Lockout.
  • Industry Standard Size.
  • Surface Mountable.
  • 1500-Vdc Isolation.
