Using The External Voltage Divider
The EP53x2Q-E evaluation board is designed to provide a great deal of flexibility
in evaluating the performance of the Enpirion DCDC module.
Pre-tinned pads are provided to place 0402 sized 1% resistors on the board to
implement an external resistor divider to choose an output voltage other than one
of the seven pre-set voltages available on the VID.
Figure 2. External divider schematic.
Figure 3 demonstrates the placement of the R1 and R2 resistors.
The output voltage is selected by the following formula:
R
The external voltage divider option is chosen by setting the jumpers VS0, VS1,
and VS2 to a logic “high”.
