AP3125V - GREEN MODE PWM CONTROLLER

Download the AP3125V datasheet PDF. This datasheet also covers the AP3125A variant, as both devices belong to the same green mode pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The AP3125A/V/L/R is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.

Key Features

  • are included, such as cycle-bycycle current limit (OCP), VCC Over Voltage Protection (VOVP), internal OTP, Over Load Protection (OLP) and pins’ fault protection. The versatile latch functions can be implemented using a minimal number of external components. (Top View) Pin 1 Mark GND 1 FB 2 CTRL 3 6 GATE 5 VCC 4 SENSE SOT26 Features.

NEW PRODUCT Description A Product Line of Diodes Incorporated AP3125A/V/L/R GREEN MODE PWM CONTROLLER Pin Assignments The AP3125A/V/L/R is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters. The PWM switching frequency at normal operation is internally fixed (about 65kHz). In middle load, the IC will enter green mode to improve system efficiency with the help of frequency foldback. A minimum switching frequency (about 20kHz) is set to avoid the audible noise. In no load or light load, the IC will enter the burst mode to minimize standby power. Furthermore, the frequency dithering function is built-in to reduce EMI emission.
