Analog Devices DC2866A Demo Board features the LTC4421 dual supply high power prioritised PowerPath controller. This demo board arbitrates between two input supply rails by selecting the highest priority and giving a valid supply to power the load.
The board considers the supply connected to V1 as the higher priority supply and provides the option to change dynamically. This demo board has external resistive dividers to set the under-voltage and overvoltage thresholds that bound the valid voltage window. The board operates at 0V to 36V voltage range.
This demo board is excellent for usage in high-reliability systems, server-based back-up systems, industrial handheld instruments, and battery back-up systems.
