AP3105
Description
Pin Assignments The AP3105/V/L/R is a low startup current, current mode PWM controller with green-mode power-saving operation. The PWM switching frequency at normal operation is set with 65kHz typically and the dithering of frequency will also improve the EMI feature.
Key Features
- About 20kHz frequency switching is to avoid the audible noise as well as reducing the standby loss
- The skip mode point can be adjusted through the external resistor connected to the current sense resistor
