This wide-input power-supply reference design is specifically designed for space-constrained automotive ADAS camera applications. This size-optimized design uses front-end protection paired with a wide input voltage DC/DC converter to enable off-battery operation. The front-end filter and component selection are optimized to comply with stringent CISPR 25 class 5 conducted electromagnetic interference (EMI) standards.
