TPS92518-Q1 Automotive Dual Channel Buck LED Controller with SPI Interface,  
Analog and PWM Dimming  
1 Features  
3 Description  
The TPS92518-Q1 family of parts are dual channel  
buck LED current controllers with  
communications interface. The serial communication  
interface provides a singular communication path for  
multichannel and platform lighting driver module  
(LDM) applications.

AEC-Q100 Qualified for Automotive Applications  
a
SPI  
Grade 1: –40°C to 125°C Ambient Operating  
Temperature  
Device HBM Classification Level H2  
Device CDM Classification Level C5  
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.  
Wide Input Voltage Range 6.5 V to 65 V  
Two independent Buck LED Controllers  
High Bandwidth, Quasi-Hysteretic Control  
Adjustable High-Side Sense  
Direct PWM Dimming Input  
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.  
Cycle-by-Cycle Current Limit  
SPI Communications Interface  
Software configurable Set Points (8-bit)  
Digital Calibration and Binning  
Fault Monitoring and Reporting  
Advanced, High Precision Dimming  
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.
