Description
Product Overview
DC1619A demonstration circuit is a 100KHz to 500KHz programmable frequency, high voltage, current mode DC/DC step-down converter featuring the LT®3845A. The operating frequency can be synchronized up to 600KHz. This demo board is designed for 12V up to 10A (120W) output from a 16V to 60V input. 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. An optional boost bias circuit is provided on the bottom side of the board for back-driving the LT3845A internal regulator from the output voltage.
