The ISL78083DEMO1Z is used to demonstrate the performance of the ISL78083 multi-output DC/DC regulator comprised of a primary high voltage synchronous buck regulator, two secondary low voltage synchronous buck regulators, and a secondary low dropout linear regulator (LDO).

The ISL78083 automotive camera power management IC is intended for high-density power applications, requiring few external components and minimal board space. The ISL78083 provides up to four regulated outputs with full protection and offers three power-good indicators and a reset/fault indicator.
