HV9931 General Description

The HV9931 is a fixed-frequency PWM controller IC designed to control an LED lamp driver using a single-stage PFC buck-boost-buck topology. It can achieve a unity power factor and a very high step-down ratio that enables driving a single high-brightness LED from 85 VAC to 264 VAC input without a pow.
