HV9931規(guī)格書詳情
General Description
The HV9931 is a fixed frequency PWM controller IC designed to control an LED lamp driver using a single-stage PFC buckboost-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 the 85-264VAC input without a need for a power transformer. This topology allows reducing the filter capacitors and using non-electrolytic capacitors to improve reliability. The HV9931 uses open-loop peak current control to regulate both the input and the output current. This control technique eliminates a need for loop compensation, limits the input inrush current, and is inherently protected from input under-voltage condition.
