This reference design is a high power, wide input voltage range circuit that uses synchronous boost controllers in a dual-phase configuration outputting four (4) switchable 12-V rails that each can supply up to 2.5 A with diagnostic features; plus a dual synchronous buck that generates two high current, lower voltage rails.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
