A6213 and A6213-1: Automotive Grade, Constant-Current PWM Dimmable Buck Regulator LED Driver

The A6213 is a single IC switching regulator that provides constant-current output to drive high-power LEDs. It integrates a high-side N-channel DMOS switch for DC-to-DC step-down (buck) conversion. A true average current is output using a cycle-by-cycle, controlled on-time method.\nOutput current i •AEC-Q100 qualified \n•Supply voltage 6 to 48 V \n•True average output current control \n•3.0 A maximum output over operating temperature range(1.5 A for A6213-1)\n•Cycle-by-cycle current limit \n•Integrated MOSFET switch \n•Dimming via direct logic input or power supply voltage \n•Internal control ;
