TPS9260x-Q1 Single- and Dual-Channel Automotive Headlight LED Driver

1 Features

3 Description

The TPS9260x-Q1 family of devices is a single-

channel and dual-channel high-side-current LED

driver. With full protection and diagnostics, this family

of devices is dedicated for and ideally suited to

automotive front lighting. The base of each

independent driver is a peak-current-mode boost

controller. Each controller has two independent

feedback loops, a current-feedback loop with a high-

side current-sensing shunt and a voltage-feedback

loop with an external resistor-divider network. The

controller delivers a constant output voltage or a

constant output current. The connected load

determines whether the device regulates a constant

output current (if the circuit reaches the current set-

point earlier than voltage set-point) or a constant

output voltage (if the circuit reaches the voltage set-

point is reached first, for example, in an open-load

condition).
