DC3151A Demo Circuit for LTC7811

Analog Devices Inc. DC3151A Demo Circuit for LTC7811 is a non-synchronous boost plus a dual synchronous buck power supply featuring the LTC7811. The demonstration circuit is designed for two buck outputs, 5V/10A, 3.3V/7A, which are supplied by a boosted 9.5V output. The buck outputs can maintain regulation over a wide input voltage range of 4.5V to 36V, suitable for automotive or other battery-fed applications. Also, the demonstration circuit uses a drop-in layout, whereas 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 LTC7811 is a 40-pin exposed pad QFN.
