KP201 - Offline Current Mode PWM Controller

General Description

KP201 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

  • Primary Side Constant-Current (CC) Control for DCM and CCM Operation.
  • ±5% CC Regulation; ±1% CV Regulation.
  • Less than 75mW Standby Power.
  • Fixed 65kHz Switching Frequency.
  • Green Mode and Burst Mode Control.
  • Very Low Startup and Operation Current.
  • Built-in Frequency Shuffling to Reduce EMI.
  • Built-in Current Mode Control with Internal Slope Compensation.
  • Built-in Line & Inductance Compensation for CC Operation.
  • Built-in Protections with Auto Recove.
