AP3103,Green PWM Controller,DIP-8

The AP3103 is a high-performance green-mode PWM controller designed for efficient power management in AC-DC converters. Its low start-up current (<15 uA) ensures fast power-up with minimal losses. With green-mode operation, the IC reduces switching losses during light-load conditions, improving overall energy efficiency.

The AP3103 features comprehensive protection mechanisms, including cycle-by-cycle overcurrent protection (OCP), overvoltage protection (OVP), and overload protection (OLP), safeguarding against power faults. Encased in a DIP-8 package, this IC is ideal for compact designs in adapters, chargers, and auxiliary power supplies.

• Versatile Green-Mode Operation: Reduces switching losses with skip mode at low loads.
