FAN102 Primary-Side-Control PWM Controller

The primary-side PWM controller significantly simplifies power supply design that requires CV and CC regulation capabilities. The FAN102 controls the output voltage and current precisely with the information in the primary side of the power supply, not only removing the output current sensing loss, .

FAN102 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:
