ALT80800KLPATR Products
Allegro Microsystems' ALT80800 is a compact, high-efficiency, low EMI LED driver for automotive lighting applications. It is a synchronous buck switching regulator that provides constant-current output to drive high-power LEDs. It integrates both high-side and low-side N-channel DMOS switches for DC-to-DC step-down conversion. Output current is user-selectable by an external current sense resistor, and output voltage is automatically adjusted to drive various numbers of LEDs in a single string.The ALT80800 is the latest release in the evolution of Allegro’s automotive buck LED drivers. It is a single-IC synchronous buck switching regulator that provides constant-current output to drive high-power LEDs. It integrates both high-side and low-side N-channel DMOS switches for DC-to-DC step-down conversion.<strong>Features:</strong> 55 VIN rating (60 V abs max) that can be used on traditional 12 V automotive and 24 V trucks, and systems using a pre-boost supply followed by the ALT80800 to drive a high number of LEDs, Integrated FETs; no need for external FET(s) or diode as part of the buck conversion and higher efficiency, Switching frequency dithering for EMI reduction; pass OEM requirements and minimize associated components, 5 VCC can be used to source up to 14 mA as a local rail (e.g., power a small uC) potentially eliminate an LDO, PWM and analog dimming options, including control for NTC temperature foldback or LED binning, Adjustable LED open fault mask setting for low VIN operation (dropout mode), Automotive LED lighting: High/low beam and matrix headlights, Front and rear fog lights, Daytime running lights, Dimmable interior lights, Other automotive lighting applications, Turn/stop lights
