PMP10352

Design files

Overview

The PMP10352 reference design is a flyback converter with a 10-14Vdc input and 48V/360mA output.  This design is well suited to provide power for Type 1 (15W) Power over Ethernet (PoE) Power Source Equipment (PSE) switches.  It can also be used for any application operating from a 12V bus that needs an isolated 48V output.

Features
  • High efficiency (88% with 360mA load)
  • Small size
  • 1500Vrms isolation
Output voltage options PMP10352.1
Vin (Min) (V) 10
Vin (Max) (V) 14
Vout (Nom) (V) 48
Iout (Max) (A) .36
Output Power (W) 17.28
Isolated/Non-Isolated Isolated
Input Type DC
Topology Flyback- Non Sync
