AP3105V Datasheet | Diodes Incorporated

A Product Line of Diodes Incorporated AP3105/V/L/R COST EFFECTIVE GREEN PWM CONTROLLER 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. When the load decreases, the frequency will reduce and when at a very low load, the IC will enter the „burst mode‟ to minimize switching loss. 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...
