Overview
NEW PRODUCT 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 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 emi...
