SLUSBP5D – MARCH 2014 – REVISED JANUARY 2015 TPS9260x-Q1 Single-and Dual-Channel Automotive Headlight LED Driver
1 Features 3 Description The TPS9260x-Q1 family of devices is a singlechannel 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 highside 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 setpoint earlier than voltage set-point) or a constant
output voltage (if the circuit reaches the voltage setpoint is reached first, for example, in an open-load
condition). 1 Qualified for Automotive Applications
