Demonstration Circuit 3001A-B showcases the LTC4451 ideal diode controller with an integrated low RDS(ON) MOSFET. The board includes two independent LTC4451 ideal diodes sharing a common ground and operates over a range of 0V to 40V, carrying up to 8A at 25°C ambient temperature. The board can be set up in a diode-OR configuration by connecting the output channels together. NOTE: Although the DC3001A-B can carry 8A at 25°C, the LTC4451 is designed for a max current of 7A across –40°C to 125°C. Please follow the data sheet recommendations to design your application across the operating temperature range.

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). Synchronization to an external clock is also possible. The LTC7817 data sheet gives a complete description of these parts, operation and application information.
