Product details

Description

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.

Features

Supply voltage 6 to 48 V.
True average output current control.
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 compensation.
Undervoltage lockout (UVLO) and thermal shutdown protection.
Low power shutdown (1 µA typical).
Robust protection against:.
Adjacent pin.
