FAN102 - Primary-Side-Control PWM Controller

General Description

The primary-side PWM controller significantly simplifies power supply design that requires CV and CC regulation capabilities.

Key Features

  • Constant-Voltage (CV) and Constant-Current (CC) Control without Secondary-Feedback Circuitry.
  • Green Mode: Frequency Reduction at Light Load.
  • Fixed PWM Frequency at 42 kHz with Frequency Hopping to Reduce EMI.
  • Cable Voltage Drop Compensation in CV Mode.
  • Low Startup Current: 10 μA.
  • Low Operating Current: 3.5 mA.
  • Peak-Current-Mode Control in CV Mode.
  • Cycle-by-Cycle Current Limiting.
  • VDD Over-Voltage Protection with Auto-Restart.
  • VDD Under-Voltage L.
