DC1717B

DC1717B is a demonstration circuit that uses the LTC®4417 (Prioritized PowerPath™ controller) to arbitrate between three input supply rails, selecting the highest priority, valid supply to power the load. The rail’s priority is defined by the input connection (V1-V3). Each rail has overvoltage and undervoltage thresholds set by external resistors. If the highest priority rail voltage falls out of the defined window (overvoltage or undervoltage), the rail with the next highest priority, which is valid, is enabled and powers the load. Two or more LTC4417s can be cascaded to provide switchover between more than three rails.

• V1 to V3, VOUT operating supply range from 2.5 to 36V
• Break-before-make time is 2µs typ at VOUT = 11V, CGATE = 10nF
• 2A typ load current
