Products Detail

The HV9931 is a constant current LED driver designed for low to medium power LED lighting without galvanic isolation. It uses a two-stage topology (buck-boost input and buck output) with a single MOSFET and control IC to achieve near unity power factor and constant current regulation. Features include output current soft start, protections (line overvoltage, load overvoltage, open circuit, and short circuit proof), and Triac dimming capability with additional components. The demo board (HV9931DB1) is configured for 120VAC input, 350mA output current, and 40V output voltage (14W).
