Description

This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides several features to enhance the performance of low-power flyback converters.

Key Features

  • Low Standby Power Under 30mW
  • High Voltage Startup
  • Fewest External ponent Counts
  • Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry
  • Green-Mode Function: Linearly-Decreasing PWM Frequency
  • Fixed PWM Frequency at 50kHz with Frequency Hopping to Solve EMI Problem
  • Cable pensation in CV Mode
  • Peak-Current-Mode Control in CV Mode
  • Cycle-by-Cycle Current Limiting
  • VDD Over-Voltage Protection with Auto Restart
