Product Details

The ADP5072CB-EVALZ evaluation board demonstrates the functionality of the ADP5072 dc to dc converter. The ADP5072 is a dual high performance dc to dc regulator that generates independently regulated positive and negative rails.

Use the board to evaluate simple device measurements, such as line regulation, load regulation, and efficiency. Device features can be demonstrated, such as selectable operating frequency, soft start, sequencing, and slew rate control.

For more details about the ADP5072, refer to the ADP5072 data sheet, which must be consulted in conjunction with this user guide when using the evaluation board.
