AP3125A/V/L/R
GREEN MODE PWM CONTROLLER
Pin Assignments
The AP3125A/V/L/R 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
Features
- are included, such as cycle-bycycle current limit (OCP), VCC Over Voltage Protection (VOVP), internal OTP, Over Load Protection (OLP) and pins’ fault protection. The versatile latch functions can be implemented using a minimal number of external components. (Top View) Pin 1 Mark
