Enhance Your Next Lighting Design with Microchip's HV9805

The HV9805 is a two-stage topology that provides true constant current drive for the LED load while drawing mains power with high power factor

The HV9805 is particularly geared to driving a high voltage LED string by means of a boundary conduction mode boost converter and a series linear current regulator. The high voltage LED string offers inherent cost advantages with respect to cooling and optics. The linear regulator provides a true constant current drive and protects the LED load from mains overvoltage.
