DC1737A

DC1737A demonstration circuit is a current-mode inverting DC/DC converter featuring the LTC®3863. The board operates from an input range of 4.5V to 16V, and provides a -5.2V, 1.7A output or a -12V, 1A output (jumper selectable). It operates at 400kHz 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. Burst Mode® operation that improves efficiency at light loads can be enabled with a jumper. A power good output signal is provided. The demonstration board has options for larger MOSFET and diode packages on the back of the board for higher output current requirements. This board is suitable for a wide range of automotive, telecom, industrial, and other applications.
