HV9805 Datasheet (Microchip) - Off-Line LED Driver

HV9805, Off-Line LED Driver

The HV9805 driver integrated circuit (IC) is targeted at general LED lighting products, such as LED lamps and LED lighting fixtures with a maximum power rating of about 25W at 120VAC and about 50W at 230VAC.

A two-stage topology provides true constant current drive for the LED load while drawing mai
