Analog Devices LTC7060 | Demoboard EVAL-LTC7872-AZ

Description

The evaluation board EVAL-LTC7872-AZ is a high power, high efficiency, four-phase bidirectional converter featuring the LTC7872 and LTC7060. The terminals labeled VHIGH and VLOW are either inputs or outputs depending on the direction of power flow. When the switch SW1 is set to the BUCK position, VLOW provides a 14V output and VHIGH is the input with a range of 30V to 75V with a maximum load current of 120A. When the switch SW1 is in the BOOST position, VHIGH provides a 48V output and VLOW is the input with a range of 10V to 14V with a maximum load current of 34A at a 14V input voltage. The maximum ILOW current is 120A in both directions. The maximum output power is 1.7kW when operating as a buck within the input voltage range. When operating as a boost, the maximum output power is 1.6kW when the input voltage is 14V. External airflow is required when operating at maximum power in either direction of power flow. The MOSFETs in each phase are driven by the LTC7060 half-bridge driver.
