The AP31261 is a current mode PWM controller which is optimized\nfor high performance, low standby power and cost effective offline\nflyback converters.\nThe PWM switching frequency at normal operation is internally fixed\n(about 65kHz). In middle load, the IC will enter green mode to\nimprove system efficiency with the help of frequency foldback. A\nminimum switching frequency (about 20kHz) is set to avoid the\naudible noise. In no load or light load, the IC will enter the burst mode\nto minimize standby power. Furthermore, the frequency dithering\nfunction is built-in to reduce EMI emission. Internal slope compensation allows more stable Peak-Current Mode\ncontrol 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 Over Voltage Protection (VOVP), internal OTP, Over Load Protection (OLP) and pins’ fault protection.
