DP2291 - Offline Current Mode PWM Controller

General Description

DP2291 is a high performance current mode PWM controller for offline flyback converter applications.

Key Features

  • General Primary Side Constant-Current (CC) Control Supports DCM and CCM Operation.
  • ± 5% CC Regulation, ± 1% CV Regulation with Fast Dynamic Response.
  • CC Algorithm Compensates for Line Variation and Transformer Inductance Tolerance.
  • Less than 75mW Standby Power for sub 30W.
