Primary-Side Regulated Flyback for Universal 3-phase AC Input w/Bipolar Transistor Reference Design

PMP9044

Design files

Overview

The PMP9044 reference design uses the UCC28720 primary-side regulated flyback controller to generate a 3.3V/0.5A output from a 3-phase univeral AC input. A bipolar transistor is used as the switch on the primary side to minimize the circuit cost.

Output voltage options PMP9044.1
Vin (Min) (V) 90
Vin (Max) (V) 265
Vout (Nom) (V) 3.3
Iout (Max) (A) .5
Output Power (W) 1.65
Isolated/Non-Isolated Isolated
Input Type AC
Topology Flyback- DCM

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
