Product Overview
EVAL-LTC7872-AZ is an evaluation board for evaluating high power, high efficiency, four-phase bidirectional converter featuring the LTC7872 and LTC7060. The terminals labelled VHIGH and VLOW are either inputs or outputs depending on 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 30 to 75V with a max 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 10 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.
- SPI-compatible port
- Pin-selectable, light-load operating modes (Buck: FCM, DCM, Burst and Boost: FCM and DCM)
- Optional jumper to enable spread-spectrum modulation
- Footprints for Optional PG-HSOF-8-1 MOSFETs and coupled inductors
- Optional UVLO circuits for VHIGH and VLOW
- SYNC, CLKOUT, RUN, FAULT, PGOOD, and PWMEN pins
- DC2026C Linduino board and QuikEval software allow: changes to DC current limit using SETCUR pin
- Increasing or decreasing the VLOW/VHIGH regulation voltage when SW1 switch Is in Buck/Boost position
- Making adjustments to frequency spread and modulation rate of spread spectrum circuit (SS is En)
- Monitoring the operational status and faults of the LTC7872
