Renesas Electronics ISL78264EVAL1Z Evaluation Board

Renesas Electronics ISL78264EVAL1Z Evaluation Board provides a demonstration and development platform for the ISL78264 Dual Synchronous Buck Controller. The ISL78264 is a dual-controller device that supports two DC-DC channels, Buck 1 and Buck 2, that can be configured in various modes and operate across a V_IN range of 3.75V to 42.0V. Buck Converter 1 can be configured as a fixed 3.3V, fixed 5.0V, or as an adjustable output Buck regulator from 0.8V to 5.0V. Buck Converter 2 has an adjustable output that can be set in the range of 0.8V to 32V.

The Renesas Electronics ISL78264EVAL1Z Evaluation Board illustrates the high efficiency of synchronous Buck operation and all the features of the ISL78264, including overcurrent protection, overvoltage, and undervoltage protection, and power-good indication for each channel. The ISL78265EVAL1Z is optimized to offer numerous test points for easy evaluation.
