DC2434A, Demo Board based on LTC3864 12V = VIN = 60V, Vout = 12V @ 5A Buck Controller
Referenzdesign von: Analog Devices
DC2434A, Demonstration circuit is a high voltage, current mode DC/DC step-down converter featuring the LTC3864. 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
