DC2434A - LTC3864 Demo Board | Buck Controller, 12V ≤ VIN ≤ 60V, Vout = 12V @ 5A

Demonstration circuit 2434A is a high voltage, current mode DC/DC step-down converter featuring the LTC®3864.

The board operates from an input range of 6V to 60V and provides a 12V, 5A output when the input exceeds 12V. The PMOSFET architecture allows it to operate seamlessly up to 100% duty cycle and function as a saturated switch below the regulation threshold, down to 6VIN. It operates at 200kHz 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.
