Demonstration circuit 2131A is a current mode DC/DC step-down Silent Switcher® buck regulator featuring the LTC3623. The board operates from an input range of 4V to 15V, and provides ±5A of output current. The output voltage of the demonstration board can be set from 0V to VIN – 0.5V. It operates at 1MHz and may be synchronized to an external clock. A soft-start feature controls output voltage slew rate at start-up, reducing current surge and voltage overshoot. A power good output and current monitor signal are provided. Discontinuous conduction mode can be selected with a jumper. The demonstration board has options for cable drop compensation, negative output voltage and input voltage regulation.
