NEW PRODUCT AP3118 HIGH-PERFORMANCE MULTI-MODE PWM CONTROLLER Description Pin Assignments The AP3118 is a Current Mode PWM controller specially designed for offline power supply that requires ultra-low standby power, highpower density and comprehensive protection. Coordinating with secondary USB PD controller, which can provide a total USB PD solution. The PWM switching frequency at normal operation is internally fixed (about 65kHz). At middle load, the IC will enter green mode, and the switching frequency will smoothly decrease along with the decreasing load. A minimum switching frequency (about 25kHz) is set to avoid the audible noise. AP3118 supports transient peak power excursion.
