Top Features

Packaging

The A6211 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.

Output current is user-selectable by an external current sense resistor. Output voltage is automatically adjusted to drive various numbers of LEDs in a single string. This ensures the optimal system efficiency.

LED dimming is accomplished by a direct logic input pulse width modulation (PWM) signal at the enable pin.

The device is provided in a compact 8-pin narrow SOIC package (suffix LJ) with exposed pad for enhanced thermal dissipation. It is lead (Pb) free, with 100% matte tin leadframe plating.

  • Supply voltage 6 to 48 V
  • True average output current control
  • 3.0 A maximum output over operating temperature range
  • Cycle-by-cycle current limit
  • Integrated MOSFET switch
  • Dimming via direct logic input or power supply voltage
  • Internal control loop compensation
  • Undervoltage lockout (UVLO) and thermal shutdown protection
  • Low power shutdown (1 μA typical)
  • Robust protection against:
    • Adjacent pin-to-pin short
    • Pin-to-GND short
    • Component open/short faults
