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).
Each controller supports all typical topologies such as boost, boost-to-battery, SEPIC, or flyback.
Uses of the high-side PMOS FET driver are for PWM dimming of the LED string and for cutoff in case of an external short circuit to GND to protect the circuit.
