Description
The A6217 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.
Features
- AEC-Q100 qualified.
- 6 to 48 V supply voltage.
- True average output current control.
- 3 A maximum output over operating temperature range
(1.5 A for A6217-1).
- Cycle-by-cycle current limit.
- Integrated MOSFET switch.
- Enable / PWM 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 typic.
