Description
Pin Assignments
The AP3127/H is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.The AP3127/H coordinating with Diodes’ secondary side controller AP4320 and protocol decoding IC AP4370 provide a Flyback charger/adapter solution compatible to Qualcomm Quick Charge 2.0 protocol.The PWM switching frequency at normal operation is internally fixed (about 65kHz for AP3127 and 100kHz for AP3127H).In middle load,
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. AP3127/H combines secondary side OVP (SOVP) and UVP. (Top View) Pin 1 Mark
