The A6214KLKTR-T is a single-IC switching regulator designed to provide a constant-current output for driving high-power LEDs. It integrates a high-side N-channel DMOS switch for DC-to-DC buck conversion, utilizing a cycle-by-cycle controlled on-time method for true average current output.
This LED driver operates with a supply voltage range of 4.5 to 55 V and can deliver up to 2 A of output current. The output current is user-selectable via an external current sense resistor. It supports PWM dimming through a direct logic input signal, allowing for precise brightness control down to 0.1% at 200 Hz. An analog dimming input is also available for brightness calibration and thermal foldback.
The A6214KLKTR-T is provided in a compact 10-pin narrow SOIC package with an exposed pad for enhanced thermal dissipation. It is AEC-Q100 qualified, making it suitable for automotive applications. The device includes robust protection features such as LED string open and short protection, cycle-by-cycle current limit, undervoltage lockout (UVLO), and thermal shutdown (TSD).
Key features include an integrated MOSFET switch, internal control loop compensation, and an integrated 5 V, 10 mA regulator for driving external loads. It is lead (Pb) free with 100% matte-tin leadframe plating.
