DC2122A - LTC3859ALEUHF Demo Board | 4.5V ≤ VIN ≤ 36V; VOUT1: 5V @ 5A, VOUT2: 8.5V @ 3A, VOUT3: 10V @ 7A

Demonstration circuit 2122A is a triple output synchronous step-up/dual step-down supply featuring the LTC®3859AL. This demonstration circuit is designed for two buck 5V/5A, 8.5V/3A outputs supplied by a boosted 10V/7A output. Benefiting from this feature, the buck outputs are able to maintain regulation over a wide input voltage range of 4.5V to 36V which is suitable for automotive or other battery fed applications. Also, the demonstration circuit uses a drop-in layout that the main buck circuit components fit in an area of ¾" by 1½", while the main boost circuit area is ¾" by 1¾". The package style for the LTC3859AL is a 38-pin exposed pad QFN package.
