AP3125B Description
A Product Line of Diodes Incorporated AP3125B GREEN MODE PWM CONTROLLER Pin Assignments The AP3125B 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 middle load, the IC will enter green mode to improve system efficiency with the help of...
