Overview
The NCV78702MW0R2G, produced by ON Semiconductor, is a single-chip, high-efficiency booster designed for smart power ballast and LED driver applications in automotive front lighting. This device is particularly suited for high current LEDs and can be used in conjunction with other components like the NCV78723 (dual channel buck) or NCV78713 (single channel) to drive multiple LED strings up to 60 V. It features a current-mode voltage boost controller that also acts as an input filter, minimizing the need for external components. The output voltage can be customized, and multiple devices can be combined to operate as a multiphase booster (2-phase, 3-phase, 4-phase), enhancing the filtering effect and reducing the total application BOM cost for higher power applications.
