Microchip TechnologyHV9805MG-GLED Drivers

This off-line LED driver IC from Microchip is geared to drive a high voltage LED load. As you know, loads arranged for high-voltage can provide real cost advantages for both heat management and optics. This driver offers true DC output current and protects the load from line voltage transients. It has a maximum power rating of about 25 Watts at 120 VAC and about 50 Watts at 230 VAC. Its boost converter has a cascode switch to allow high-speed switching and convenient generation of V_DD supply. The control device for this cascode switch is an integral part of the off-line LED driver and is rated at 700 mA. This off-line LED driver was designed for general LED lighting products such as LED lamps and LED lighting fixtures. It’s also compatible with SEPIC topology for low output voltage applications.
