The TPS92518-Q1 family of parts are dual channel buck LED current controllers with a SPI communications interface. The serial communication interface provides a singular communication path for multichannel and platform lighting driver module (LDM) applications.

The TPS92518-Q1 uses a quasi-hysteretic control method that supports switching frequencies ranging from 1 kHz to 2 MHz. This control method enables superior, high frequency shunt FET dimming and also handles the demanding dynamic loads of adaptive LED matrix based headlamp systems.

Software programmable SPI set points (Precision Peak Current, Controlled Off-Time and Output Voltage Sense) enables designers to develop a single LED driver solution for multiple load configurations that can be quickly reconfigured for future LED driver design requirements.

The TPS92518-Q1 device has an input range up to 42 V. The TPS92518HV-Q1 is a high-voltage option with an input range up to 65 V.
