Product Details
The EVAL-LTM4682-A1Z evaluation board features the LTM®4682: the wide input and output voltage range, high efficiency and power density, quad output PolyPhase® DC-to-DC step-down μModule® (micromodule) power regulator with digital power system management (PSM). The EVAL-LTM4682-A1Z evaluation board is configured as a 4-phase four output. A similar evaluation board with a 4-phase single output is also available (EVAL-LTM4682-A2Z).
The EVAL-LTM4682-A1Z evaluation board’s default input voltage range is 4.5V to 16V. However, if VIN is lower than 6V and within 4.5V ≤ VIN ≤ 5.75V, a minor modification to certain existing on-board components is required. See step 8 (Operation at Low VIN: 4.5V ≤ VIN ≤ 5.75V) in the Procedure section.
The factory default output voltage VOUT [0:3] is 0.7V at 31.25A maximum load current per channel. Each channel can deliver up to 31.25A maximum load current, but forced airflow and heatsink might also be used to further optimize the output power when all output rails are on and fully loaded. The evaluation board output voltages can be adjusted from 0.7V up to 1.35V. Refer to the LTM4682 data sheet for thermal derating curves and recommended switching frequency when adjusting the output voltage.
