Description
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.
Features
- No additional components required for direct connection to battery
- Overall solution size of 1272 mm2 for ADAS camera modules
- Wide 4-V to 36-V input range supports start-stop and load dump operation
- Designed to protect against reverse battery condition
- Tested against CISPR 25 class 5 conducted EMI standards
