Renesas Electronics ISL78263EVAL1Z Evaluation Board

Renesas Electronics ISL78263EVAL1Z Evaluation Board provides a demonstration and development platform for the ISL78263 Cold Crank Boost and Buck Controller. The ISL78263 is a dual-controller device that supports two DC-DC channels, Boost and Buck, with each supporting multiple configurations. Channel 1 operates as a Buck converter and can be configured as a fixed 3.3V, fixed 5.0V, or as an adjustable output voltage from 0.8V to 5.0V. Channel 2 is a Boost circuit that can be configured to operate in individual Boost and Cold Crank Boost.

The Renesas Electronics ISL78263EVAL1Z Evaluation Board supports the demonstration of the ISL78263, offering a power solution design that provides a system rail voltage capable of withstanding automotive cold crank applications. The Evaluation Board also enables the evaluation of features such as overcurrent protection, overvoltage and undervoltage protection, and power-good indicators for each channel. The ISL78263EVAL1Z is optimized to offer numerous test points for easy evaluation.
