1 / 14 page AP3102/V/L Document number: DS37419 Rev.2 - 2 1 of 14 www.diodes.com July 2014 © Diodes Incorporated AP3102/V/L A Product Line of Diodes Incorporated GREEN MODE PWM CONTROLLER Description 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, and 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. The AP3102/V/L series features a lot of functions such as the Leading-Edge Blanking (LEB) of the current sensing, internal slope compensation, line compensation, and several protection functions including cycle-by-cycle current limit (OCP), over voltage protection (VCC or line voltage), OTP, OLP and brownout protection. The AP3102/V/L series provides 3 different versions with optional protection functions. AP3102 has external trigger latch shutdown only (VOVP and OLP are auto recoverable). AP3102V supports both VOVP and external latch shutdown. AP3102L provides latch shutdown control for VOVP, OLP and external trigger. This IC is available in SO-8 package.
