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...
