The TPS92520-Q1 is a monolithic dual synchronous buck LED driver with a wide 4.5-V to 65-V operating input voltage range. It independently powers two strings of series-connected LEDs using adaptive on-time average current mode control. The device is designed for compatibility with shunt FET dimming and LED matrix manager-based dynamic beam headlamps, featuring a Serial Peripheral Interface (SPI) for fault monitoring, reporting, and configuration of parameters like switching frequency and PWM duty cycle.
