FL663 - Primary-Side-Regulation PWM Controller

General Description

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

Key Features

  • Low Standby Power: < 30 mW.
  • High-Voltage Startup.
  • Few External Component Counts.
  • Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry.
  • Green-Mode: Linearly-Decreasing PWM Frequency with Cycle skipping.
  • Fixed PWM Frequency at 50 kHz and 33 kHz with Proprietary Frequency Hopping to Solve EMI Problems.
  • Peak-Current-Mode Control in CV Mode.
  • Cycle-by-Cycle Current Limiting.
  • VDD Over-Voltage Protection (OVP).
  • V.
