60V, Synchronous Buck LED Driver Delivers Over 300W of LED Power
The LT3763 uses two external switching MOSFETs and can deliver from 5W to over 300W of continuous LED power with efficiencies up to 96%. LED current accuracy of ±6% ensures constant lighting while ±1.5% output voltage accuracy offers several LED protection features and also enables the converter to operate as a constant voltage/constant current source for charging applications. The LT3763 can utilize either analog or PWM dimming as required by the application. Furthermore, its switching frequency can be programmed between 200kHz and 1MHz or synchronized to an external clock. Additional features include open/short protection, C/10 detection, input and output current monitors, and integrated fault protection.
The LT3763EFE is available in a 28-lead thermally enhanced TSSOP package, priced starting at $4.45 each, in 1,000-piece quantities. An extended temperature version, or I grade, the LT3763IFE, is also available, priced starting at $4.90 each in 1,000-piece quantities. Furthermore, a high temperature version, or H grade, the LT3763HFE, is also available, priced starting at $5.15 each in 1,000-piece quantities. All versions are available from stock.
