onsemi LED Drivers NCV78703MW1R2G

The NCV78703MW1R2G is a high-efficiency multiphase booster LED driver designed for automotive front lighting applications, including high beam, low beam, daytime running lights, and turn indicators. This single-chip solution supports high current LEDs and can drive multiple LED strings with output voltages customizable up to 60 V. It features a current-mode voltage boost controller that minimizes the need for external components and includes an active input filter to reduce current ripple from the battery. The device allows for the combination of multiple units to operate in a multiphase configuration, enhancing the filtering effect and potentially lowering the overall bill of materials cost for higher power applications. It supports SPI programmability for dynamic control of system parameters and includes features such as programmable input current limitation, integrated failure diagnostics, and a fail-safe operating mode. The NCV78703MW1R2G is packaged in a QFN24 format, making it suitable for compact designs.
