| IC revision | A |
Description
Demonstration circuit 2434A is a high voltage, currentmodeDC/DC step-down converter featuring the LTC®3864.The board operates from an input range of 6V to 60V andprovides a 12V, 5A output when the input exceeds 12V.The PMOSFET architecture allows it to operate seamlesslyup to 100% duty cycle and function as a saturated switchbelow the regulation threshold, down to 6VIN. It operatesat 200kHz and may be synchronized to an external clock.A soft-start feature controls output voltage slew rate atstart-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 outputsignal is provided.This board is suitable for a wide range of automotive,telecom, industrial and other applications. The LTC3864is available in small 12-pin thermally enhanced MSOP andDFN packages. For other output requirements, see theLTC3864 data sheet or contact the LTC factory.
