Datasheet ISL78083 Automotive Camera Power Management IC with Three Synchronous Buck Regulators and One Low Dropout Linear Regulator The ISL78083 is a versatile multi-rail power IC comprised of a primary high voltage synchronous buck regulator, two secondary low voltage synchronous buck regulators, and an LDO regulator. It also offers four overvoltage and undervoltage monitors, three power-good indicators, and a reset output/fault indicator. To limit common-cause failures, the ISL78083 also includes a second reference for the OV/UV monitors, independent from the reference of the regulators. The ISL78083 is intended for high-density power applications, requiring few external components and minimal board space.
