DP2293 - Offline Current Mode PWM Controller

General Description

DP2293 is a high performance current mode PWM controller for offline flyback converter applications.

It supports DCM and CCM operation.

In DP2293, PWM switching frequency with shuffling is fixed to 65 KHz and is trimmed to tight range.

Key Features

  • Support DCM and CCM Operation.
  • ±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 Protections with Auto Recovery:.
  • VDD Under Voltage Lockout (UVLO).
  • VDD Over Voltage Protection (OVP).
  • Input Brownout Protection (Brown.
