DC2348A-A

DC2348A-A demonstration circuit is a high power high high-efficiency bi-directional synchronous buck or boost converter featuring the LTC®3871. The DC2348A-A operates with two each LTC3871 devices with four phases. When operating in buck mode, this demo circuit has an input voltage range of 30V to 75V and produces a 12V output. When operating in boost mode, the input voltage is from 10V to 13V and produces a 48V output voltage. The board has a switch that allows the converter to run in either buck or boost mode. A DC voltage source can be connected to the SETCUR turret to set the average inductor current in each phase of the converter. The board also utilize a mode jumper to select forced continuous conduction mode, buck-mode only pulse-skipping or full pulse-skipping mode for buck and boost.

• 60A output current (Buck mode)
• 15A output current (boost mode)
• 110KHz operating frequency (Buck mode)
• 110KHz operating frequency (Boost mode)
• 97.5% efficiency at 48V to 12V at 60A and 97% efficiency at 12V to 48V at 15A
