Maxim Integrated's Automotive Backlight Driver with Integrated Boost Converter Sustains Full, Constant Brightness of In-Car Displays Even During Cold Crank Conditions

LED driver with four 120mA channels features industry's lowest input voltage and highest efficiency in a single chip

SAN JOSE, Calif., July 6, 2021 — (PRNewswire) —  Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduces the four-channel, low-voltage MAX25512 automotive LED backlight driver with integrated boost converter. It is the only integrated solution that retains full, constant brightness of in-car displays even during extreme cold crank conditions down to 3V input voltage. The single chip LED driver eliminates an external MOSFET and current sense resistor and integrates I2C communication to lower bill of material cost and reduce board space by 30 percent. The highly integrated LED driver includes four 120mA channels with the industry's highest efficiency at 2.2MHz operation.

Today's automotive start-stop systems increase fuel economy, but they can challenge the power delivery system to maintain the same level of display brightness during re-start. For example, features like display illumination upon entry can be affected by cold crank situations, with the engine drawing down the car battery enough to cause the display to turn off and back on. Maxim Integrated's MAX25512 LED backlight driver operates down to 3V after startup without the addition of a pre-boost converter, protecting the display from these power disruptions.
