TPS92550 & TPS92551 450mA Buck LED Drivers

Texas Instruments TPS92550 Constant Current Buck LED Driver Micro-Module drives maximum 450mA LED current up to 10 LEDs in a single string (maximum 14W) while the TPS92551 Constant Current Buck LED Driver Micro-Module drives maximum 450mA LED current up to 16 LEDs in a single string (maximum 23W). These National Products from TI LED driver micro-modules integrate all the power components, including the power inductor. TPS92550 and TPS92551 provide a full turn-key, highly efficient solution for a wide range of single-string LED lighting applications with up to 96% power efficiency for TPS92550 and 95% for TPS92551. TPS92550 accepts an input voltage ranging from 4.5V to 36V and delivers a 350mA LED current as default.
