Overview
NEW PRODUCT A Product Line of Diodes Incorporated AP3125HA/HB GREEN MODE PWM CONTROLLER Description Pin Assignments The AP3125HA/HB 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 100kHz).
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.
Internal line compensation ensures constant output power limit over entire universal line voltage range.
Comprehensive protection features are included, suc...
