Product Overview
DC1909A demonstration circuit is a 150KHz, 60V current mode DC/DC step-down converter with accurate current limit featuring the LT®3840. The circuit operates from a VIN range of 4.5V to 60V, survives an 80V transient, and outputs 3.3V at 20A (66W). An integrated buck-boost switching regulator generates a 7.5V bias supply voltage for MOSFET gate drive and IC power to increase the overall efficiency by reducing the power loss. A soft-start feature controls the output voltage slew rate at start-up, reducing current surges and voltage overshoots. The modes of operation (Burst Mode®, discontinuous current mode and continuous current mode) are jumper selectable. Both Burst Mode operation and discontinuous current mode increase the efficiency at light loads. Continuous current mode will maintain a constant switching frequency regardless of the load current. This board is suitable for a wide range of automotive, telecom, industrial, and other applications.
