Demonstration circuit 2738A is a triple output synchronous step-up/dual step-down supply featuring the LTC®7815. The demonstration circuit is designed for two buck 5V/8A, 3.3V/8A outputs supplied by a boost 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 three-quarter inches by 1.5 inches, while the main boost circuit area is three-quarter inches by 1.75 inches. The package style for the LTC7815 is a 38-pin exposed pad QFN.
