Demonstration circuit 3033A is a triple output synchronous step-up/dual step-down supply featuring the LTC7817. The demonstration circuit is designed for two buck outputs 5V/10A, 3.3V/10A supplied by a boosted 10V 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 whereas the main buck circuit components fit in an area of ¾-inch by 1½-inch, while the main boost circuit area is ¾-inch by 1¾-inch. The package style for the LTC7817 is a 38-pin exposed pad QFN. The main features of the board include rail tracking (buck channels only), an internal 5V linear regulator for bias, separated RUN pins for each output, a PGOOD signal (CH1 only), and a mode selector that allow the converter to run in forced continuous mode (FCM), pulse-skipping (PSM) or Burst Mode® operation (BURST).
