The A6217KLJTR-1-T is an automotive-grade constant-current PWM dimmable buck regulator LED driver designed to deliver up to 1.5 A output current, with an operating supply voltage range of 6 to 48 V. It features an integrated high-side N-channel DMOS switch, cycle-by-cycle current limit, and direct logic-level PWM dimming via the enable pin. The device is packaged in an 8-pin narrow SOIC with an exposed thermal pad for enhanced heat dissipation and meets AEC-Q100 qualification. It includes undervoltage lockout, thermal shutdown, and protection against pin-to-pin shorts and component faults. Maximum junction temperature is 150 °C, with a thermal resistance of 35 °C/W from junction to ambient on a 4-layer PCB.
The A6217-1 provides a robust and efficient solution for driving high-power LEDs in automotive applications, offering constant-current output up to 3A (1.5A for A6217-1) and PWM dimming.
