By Technology
The NCV78703 is a single−chip and high efficient booster for smart Power ballast and LED Driver designed for automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78703 is in particular designed for high current LEDs and with NCV78723 (dual channel buck)/713 (single channel) provides a complete solution to drive multiple LED strings of up−to 60 V. It includes a current−mode voltage boost controller which also acts as an input filter with a minimum of external components. The available output voltage can be customized. Two devices NCV78703 can be combined and the booster circuits can operate together to function as a multiphase booster (2−phase, 3−phase, 4−phase, 5−phase, 6−phase) in order to further optimize the filtering effect of the booster and lower the total application BOM cost for higher power. Thanks to the SPI programmability, one single hardware configuration can support various application platforms.
Use the NCV78703 Boost Application SystemVision design and simulation environment to verify parametric and functional performance, and gain a better understanding of the features and behavior through live, virtual testing.

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
