The TPS92520-Q1 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 series-connected LED strings. 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 offers programmable switching frequencies from 100 kHz to 2.2 MHz, with up to 1.6 A of continuous output current and 4% accuracy. Advanced dimming operations include 10-bit precision analog dimming and 10-bit precision internal PWM dimming, with support for external PWM dimming input. It also features cycle-by-cycle switch overcurrent protection and switch thermal protection.
The device is AEC-Q100 qualified for automotive applications, operating within a temperature range of -40°C to 125°C. It is supplied in a 32-HTSSOP package suitable for surface mounting.
Key features include SPI control for configurable analog reference, switching frequency, and PWM dimming duty cycle, along with fault monitoring and reporting capabilities. It also supports limp-home (LH) and stand-alone mode operation.
