Texas Instruments TPS92518HV Dual Buck LED Controllers with SPI Interface, Analog and PWM Dimming are ideal for multichannel and platform lighting driver module (LDM) applications. The TPS92518HV LED Controllers apply a high-voltage option with an input range of up to 65V. A quasi-hysteretic control method in the Texas Instruments TPS92518HV supports switching frequencies ranging from 1kHz to 2MHz, enabling superior, high-frequency shunt FET dimming. Additionally, the control method handles demanding dynamic loads of adaptive LED matrix-based headlamp systems. Software programmable SPI set points such as Precision Peak Current, Controlled Off-Time, and Output Voltage Sense Software allow designers to develop a single LED driver solution for multiple load configurations. These SPI set points can be rapidly reconfigured for future LED driver design requirements.
