The TPS92520QDAPRQ1 from Texas Instruments is a monolithic dual synchronous buck LED driver with a wide 4.5-V to 65-V input voltage range, capable of independently powering two strings of series-connected LEDs. It implements an adaptive on-time average current mode control, compatible with shunt FET dimming techniques and LED matrix manager-based dynamic beam headlamps.
This LED driver features programmable switching frequencies from 100-kHz to 2.2-MHz, ensuring flexibility in design. It supports advanced dimming operations including 10-bit precision analog dimming and 10-bit precision internal PWM dimming, as well as external PWM dimming input. The device provides up to 1.6-A continuous output current with 4% accuracy over a wide range of input voltages, output voltages, and ambient temperatures.
For enhanced system reliability and diagnostics, the TPS92520QDAPRQ1 incorporates cycle-by-cycle switch overcurrent protection, switch thermal protection, and SPI-programmable fault monitoring and reporting. It is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to 125°C.
The device is supplied in a 32-pin HTSSOP package, suitable for surface mounting. Its applications include automotive headlights and adaptive LED driving modules.
