AP3125A 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.
