A6211 Overview
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.
A6211 Key Features
- Supply voltage 6 to 48 V

- 3 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 pensation
- Undervoltage lockout (UVLO) and thermal shutdown
- Low power shutdown (1 µA typical)
- Robust protection against
