パワー・マネージメント LEDドライバ Offline LED Driver

Offline LED Driver

The LT3799 is an isolated LED controller with active power factor correction (PFC), specifically designed for driving LEDs from a universal input range of 90VAC to 265VAC. The LTC3799 is optimized for LED applications requiring 4W to over 100W of LED power and also compatible with standard TRIAC in-wall dimmers. The LT3799’s unique current sensing scheme delivers a well regulated current to the secondary side without using an opto-coupler. This not only reduces cost but also improves reliability. Its single stage PFC regulator design requires minimal external components. Additionally, its thermally enhanced MSOP-16E package ensures a simple and compact solution footprint for off-line LED applications.
