Restrictions:

Zentrum Mikroelektronik Dresden AG’s ZSPM8825-KIT Evaluation Kit hardware and the Pink Power Designer™ software

are designed only for evaluation of the ZSPM1025D PWM Controller IC and the Murata OKLP-X/25-W12-C Power Block;

laboratory setup; and module development. The kit hardware and software must not be used for module production and

production test setups.

Zentrum Mikroelektronik Dresden AG (ZMD AG, ZMDI) shall not be liable for any damages arising out of defects resulting

from (i) delivered hardware and software, (ii) non-observance of instructions contained in this manual, or (iii) misuse,

abuse, use under abnormal conditions, or alteration by anyone other than ZMD AG. To the extent permitted by law, ZMD

AG hereby expressly disclaims and User expressly waives any and all warranties, whether express, implied, or statutory,

including, without limitation, implied warranties of merchantability and of fitness for a particular purpose, statutory warranty

of non-infringement, and any other warranty that may arise by reason of usage of trade, custom, or course of dealing.

Important Safety Warning:

These procedures can result in high currents, which can cause

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

Ensure that all staff have read and understood this document and the high voltage safety

disclaimer that is included with the kit.

ZSPM8825-KIT

Evaluation Kit for the ZSPM1025D Controller

2.1.

ZSPM8825 Evaluation Board

Evaluation Board Overview

The ZSPM8825 Evaluation Kit provides all the necessary components for a first evaluation of ZMDI’s

ZSPM1025D digital PWM controller. The ZSPM1025D can be configured using the two pin-strap resistors to

select the output voltage and the control loop performance. See the

ZSPM1025D Data Sheet

for more details.

In addition to the ZSPM1025D controller, the Evaluation Board features the Murata OKLP-X/25-W12-C Power

Block. The number of output capacitors can be selected with a jumper on the Evaluation Board. The electrical

specifications can be found in Table 2.1, and the schematic is provided in Appendix B.

Value

Important:

The Murata OKLP-X/25-W12-C Power Block has an output power limit of 49.5W. The maximum output current is therefore

a function of the output voltage.

The board also provides the connections needed for digital communication between the ZSPM1025D and the GUI

software via the PMBus™ Communications Interface (CI).

An on-board transient load is also provided for generating load transients with high current slew rates.

Figure 2.1 shows the ZSPM8825 Evaluation Board and the board connections that will be completed in the

subsequent setup steps. Do not make the connections at this point. Note that some settings for the DIP switches

are not allowed; therefore, before using the kit, ensure that switches 1 and 5 are in the “ON” position and the rest

of the switches are in the “OFF” position as shown in Figure 2.1.
