AP3125A GREEN MODE PWM CONTROLLER Description The DIODES™ AP3125A is a current mode PWM controller 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 middle load, the IC will enter green mode to improve system efficiency with the help of frequency foldback. A minimum switching frequency (about 20kHz) is set to avoid the audible noise. 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.
