A6217KEJTR-1-J

Overview

The A6217KEJTR-1-J is an automotive-grade, constant-current PWM dimmable buck regulator LED driver from Allegro MicroSystems. It integrates a high-side N-channel DMOS switch to drive high-power LEDs with a single output. The device operates within a supply voltage range of 6V to 48V and delivers up to 3A of output current per channel. It supports PWM dimming for precise light control and functions reliably across a junction temperature range of -40°C to 150°C. The component is housed in a compact 10-DFN (3x3) package.
