GREEN MODE PWM CONTROLLER General Description
Features
AP3102/V/L
The AP3102/V/L series is a green-mode PWM controller with low start-up current. At normal operation, the switching frequency is externally programmable and trimmed to tight range, the frequency dithering technique is also equipped to improve the EMI performance. When the load is very low or zero, the IC enters green mode and skip mode to minimize switching loss. In skip mode, the PWM switching frequency is about 20kHz to avoid the audible noise and reduce the standby loss.
