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
- VIN operating range from 4.0V to 42V with a start range of 4.5V to 42V
- Fixed switching frequency of 2.2MHz with optional pseudo-random spread spectrum
- Three synchronous bucks with internal compensation and one LDO
- Buck1 output range of 3.3V to 5.05V
- Buck2 output range of 1.0V to 3.3V
- Buck3 output range of 1.0V to 3.3V
- LDO4 output range of 2.8V to 3.4V
- Output UV/OV thresholds, OTP of ±4%, ±6%, ±8%, ±12%
- OTP power up/down sequence and delay
- Optional output discharge on Buck2, Buck3, and LDO4
- Current at VIN input under shutdown: <1µA typical
- Protection features
