HV9805 Datasheet - Microchip

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.
