TPS92518 Overview
The TPS92518 family of parts are dual channel buck LED current controllers with a SPI munications interface. The serial munication interface provides a singular munication path for multichannel and platform lighting driver module (LDM) applications. The TPS92518 uses a quasi-hysteretic control method that supports switching frequencies ranging from 1 kHz to 2 MHz.
