Microchip Technology HV9923N3G LED Driver IC
The HV9923 is a high-efficiency, PWM LED driver control IC suitable for low power and decorative lighting applications. It operates from universal 85-265VAC or 20-400VDC sources and delivers a constant 30mA output current through a fixed off-time buck converter topology. Incorporating an internal 475V power MOSFET, it provides reliable, regulated illumination by controlling LED strings in series. Its compact design and compatibility with triac dimmers make it ideal for modern lighting fixtures, ensuring efficient energy use and consistent brightness across varying input voltages.
