A6217 Auto PWM Dimmable Buck Regulator LED Drivers

Allegro MicroSystems A6217 Auto PWM Dimmable Buck Regulator LED Drivers offer a 6V to 48V supply voltage range, 3A maximum output, and are AEC-Q101 qualified. The A6217 is a single IC switching regulator that provides constant-current output to drive high-power LEDs. These drivers integrate a high-side N-channel DMOS switch for DC-to-DC step-down (buck) conversion. The dimmable design is accomplished when the output voltage is automatically adjusted to drive various numbers of LEDs in a single string, ensuring optimal system efficiency. LED dimming is achieved by a direct logic input pulse-width-modulation (PWM) signal at the enable pin. Allegro MicroSystems A6217 Auto PWM Dimmable Buck Regulator LED Drivers are available in a 3mm x 3mm wettable flank 10-pin DFN package or an 8-pin narrow SOIC package.
