DC2719A is a LT8708/LT8708-1 80V VIN and VOUT synchronous 4-switch buck-boost DC/DC controller with flexible bidirectional capability demonstration board. Demonstration circuit 2719A is a high performance bidirectional buck-boost converter featuring the LT®8708/ LT8708-1 that can operate from input voltages above, below or equal to the output voltage. The demo board input range is 10.5V to 14.5V (25VMAX). The output voltage is set at 14.5V and the output current limit at 40A. The LT8708 is capable of bidirectional operation when operating in the continuous conduction mode (CCM). DCM, HCM and Burst Mode operation only allow power to flow in one direction. Additional circuitry may be needed depending on the application.
