Renesas Electronics ISL78083DEMO1Z Demonstration Board
The Renesas Electronics ISL78083DEMO1Z Demonstration Board is used to demonstrate the performance of the ISL78083 multi-output DC/DC regulator. The regulator is 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.Features
