TPS92602-Q1 Automotive Headlight LED Driver

Texas Instruments TPS9260x-Q1 Automotive Headlight LED Driver is a dual-channel high-side-current LED driver. With full protection and diagnostics, the Texas Instruments TPS9260x-Q1 is dedicated to and ideally suited to automotive front lighting. The base of each independent driver is a peak-current-mode boost controller. Each controller has a current-feedback loop with a high-side current-sensing shunt and a voltage-feedback loop with an external resistor divider network. 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 the 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).
