TPS92518 Dual Channel Buck LED Controller with SPI Interface,  
Analog and PWM Dimming  
1 Features  
3 Description  
The TPS92518 family of parts are dual channel buck  
LED current controllers with a SPI communications  
interface. The serial communication interface  
1
Wide Input Voltage Range 6.5 V to 65 V  
Two independent Buck LED Controllers  
High Bandwidth, Quasi-Hysteretic Control  
Adjustable High-Side Sense  
provides  
a
singular communication path for  
multichannel and platform lighting driver module  
(LDM) applications.  
Direct PWM Dimming Input  
The TPS92518 uses  
a quasi-hysteretic control  
Cycle-by-Cycle Current Limit  
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.  
SPI Communications Interface  
Software configurable Set Points (8-bit)  
Digital Calibration and Binning  
Fault Monitoring and Reporting  
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.  
Advanced, High Precision Dimming  
10,000:1 PWM Dimming Range  
255:1 Analog Dimming Range  
High Frequency Shunt FET Dimming  
2 Applications  
The TPS92518 device has an input range up to 42 V.  
The TPS92518HV is a high-voltage option with an  
input range up to 65 V.
