FAN102 Overview
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, but eliminating all secondary feedback circuitry. The green-mode function with a low startup current (10 µA) maximizes...
