AK8817VQ General Description

The AK8817VQ is a cutting-edge voltage-mode PWM controller that has been specifically engineered for use in isolated flyback and forward converters. This high-performing device boasts a generous input voltage range of 4.5V to 30V and has the capacity to support outputs of up to 1.5A. What sets this controller apart is its green-mode feature, which significantly enhances efficiency at lighter loads, as well as a built-in soft-start function that ensures optimal startup performance. Its fixed switching frequency of 65kHz serves to minimize electromagnetic interference (EMI), while its comprehensive protection features - including overvoltage, overcurrent, and overtemperature protection - guarantee enhanced safety and longevity
