SP201 - Offline Current Mode PWM Controller

General Description

SP201 is a high performance current mode PWM controller for offline flyback converter applications.

The IC has built-in General Primary Side CC control, which simplifies isolated power supply design that requires CC regulation of the output.

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.
