TPS92520-Q1 Synchronous Buck LED Driver

Texas Instruments TPS92520-Q1 Synchronous Buck LED Driver is a monolithic dual synchronous buck LED driver with a wide 4.5V to 65V operating input voltage range that can independently power two strings of series-connected LEDs. The TPS92520-Q1 implements an adaptive on-time average current mode control and is designed to be compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps. The adaptive on-time control provides a near-constant switching frequency that can be set between 100kHz and 2.2MHz. The Texas Instruments TPS92520-Q1 inductor current sensing and closed-loop feedback enables better than ±4% accuracy over wide input voltage, output voltage, and ambient temperature range.
