Automotive Grade, Constant-Current 3-Ampere

PWM Dimmable Buck Regulator LED Driver

Description

The A6213 is a single IC switching regulator that provides

constant-currentoutputtodrivehigh-powerLEDs.Itintegrates

Features and Benefits

• AEC-Q100 qualified

• Supply voltage 6 to 48 V

ahigh-sideN-channelDMOSswitchforDC-to-DCstep-down

(buck) conversion. A true average current is output using a

cycle-by-cycle, controlled on-time method.

• True average output current control

• 3.0 A maximum output over operating temperature range

• Cycle-by-cycle current limit

• Integrated MOSFET switch

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.

• Dimming via direct logic input or power supply voltage

• Internal control loop compensation

• Undervoltage lockout (UVLO) and thermal shutdown

protection

LED dimming is accomplished by a direct logic input pulse

width modulation (PWM) signal at the enable pin.

• Low power shutdown (1 μA typical)

• Robust protection against:

▫ Adjacent pin-to-pin short

▫ Pin-to-GND short

▫ Component open/short faults
