FSEZ1317 - Primary-Side-Regulation PWM

General Description

This third-generation Primary-Side-Regulation (PSR) and highly integrated PWM controller provides several

Key Features

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