TPS92518HV Dual Buck LED Controllers

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.
