Upon start-up of the GUI, a wizard will guide the user through a simple selection process. The wizard will select

the correct configuration data for the ZSPM1025D controller.

The Side Panel

The side panel provides information about the status of the PMBus™ CI and the device connected to the

PMBus™ CI.

The Status & Monitor Tab

The “Status & Monitor” provides monitoring of voltage, current, and temperatures. The status of the internal fault

monitoring is shown.

The CONTROL pin of the ZSPM1025D can be toggled to enable or disable the output of the ZSPM8825

Evaluation Kit Setup for a 1.5V Output Voltage

This section covers the steps for powering up the ZSPM8825 Evaluation Kit for the first time.

cause severe injury or death. Only trained professional staff should connect external equipment.

Do not enable the power supply connected to the input terminals until indicated in the following

steps.

Follow these step-by-step instructions to power up the ZSPM8825 Evaluation Board:

Step 1:

Set switches 1 and 5 on DIP switch J5 to ON and make sure no jumper is placed on header J7. The

remainder of the switches must be in the OFF position. This selects the standard configuration for the

ZSPM8825 Evaluation Board. The standard configuration has an output voltage of 1.50V and operates

with the lowest output capacitor range.

Step 2:

Connect the power supply to the connectors labeled CON1 (VINP in Figure 2.1) and CON2 (PGND).

Connect the load to the CON3 (VOUT) and CON4 (PGND) connectors. The load can be either a

resistor or an electronic load. Connect the PMBus

™ CI to connector J3 (see Figure 5.1) and to a USB

port on the user’s PC.

Step 3:

Start the Pink Power Designer™ and follow the instructions given in Pink Power Designer™ Graphic

User Interface (GUI) Guide for the ZSPM1025C/D to select the Murata OKLP-X/25-W12-C Power Block

and the ZSPM1025D controller via the Murata Power Block Wizard. Then c

lick “Finish” to proceed to

the main window of the GUI.
