RPL-20-EVM-1 is an evaluation platform for RPL-20 buck regulator module. It generates a constant output voltage selectable from 1.0V, 1.2V, 1.8V, 2.5V, 3.3V and 5V from a DC input in the range of 4 to 16V. It has a maximum continuous output current of 20A. Switching frequency can be set from 600KHz, 800KHz and 1000KHz in PSM mode or FCCM mode. All the functions of the RPL-20 such as output voltage selection, mode/frequency selection, control, power good, Soft start time, Over current protection (OCP), Under voltage lockout (UVLO), trim and output sense can be readily evaluated. Also, the behavior in overload or over-temperature can be evaluated easily before it is designed in. The evaluation board also contains the filter components to meet EMC Class B levels. Alternate component positions are included to allow experimentation to optimize the EMC performance depending on operating conditions and budget.
