The AP3125CM is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.
The PWM switching frequency at normal operation is internally fixed (about 65kHz). In no load or light load, the IC will enter the burst mode to minimize standby power. Furthermore, the frequency dithering function is built-in to reduce EMI emission.
Internal slope compensation allows more stable Peak-Current Mode control over wide range of input voltage and load conditions. Internal line compensation ensures constant output power limit over entire universal line voltage range.
Comprehensive protection features are included, such as cycle-bycycle current limit (OCP), VCC Overvoltage Protection (VOVP), internal OTP, Overload Protection (OLP) and pins’ fault protection. AP3125CM combines secondary side OVP (SOVP) and external OTP.
