Product details

Description

The A6214 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.
Supply voltage 4.5 to 55 V.
2 A maximum output over operating temperature range.
Integrated MOSFET switch.
Able to use either Schottky or silicon low-side diode.
True average output current control.
Internal control loop compensation.
Integrated 5 V, 10 mA regulator for driving external load.
PWM dimming via direct logic input down to 0.1% at 200 Hz.
Standalone internal PWM dimming (A62.
