Introduction
This document describes the use of ZMDI’s ZSPM8835-KIT for evaluating DC/DC point-of-load (POL) applica-
tions and provides additional kit information, including the circuit diagram and board layout. The kit incorporates
ZMDI’s ZSPM1035D digital PWM controller IC and the Murata OKLP-X/35-W12-C Power Block to form a “smart”
buck converter (a.k.a. step-down DC-to-DC converter).
The ZSPM8835-KIT Evaluation Kit hardware functions with the ZSPM1035D Pink Power Designer™ graphical
user interface (GUI), which is used for monitoring the internal measurements and fault conditions of the
ZSPM1035D. The GUI software must be downloaded to the user’s PC from the ZMDI website to ensure receiving
the latest release as described in section 3. See section 2.2.2 for the requirements for the user’s PC.
The PMBus™ Communication Interface (CI) provides the interface between the ZSPM8835-KIT Evaluation Kit
and the user’s PC.

ZSPM8835 Evaluation Board
Evaluation Board Overview
The ZSPM8835 Evaluation Kit provides all the necessary components for a first evaluation of ZMDI’s
ZSPM1035D digital PWM controller. The ZSPM1035D can be configured using the two pin-strap resistors to
select the output voltage and the control loop performance. See the
ZSPM1035D Data Sheet
for more details.
In addition to the ZSPM1035D controller, the Evaluation Board features the Murata OKLP-X/35-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.

Important:
The Murata OKLP-X/35-W12-C Power Block has an output power limit of 82.5W. The maximum output current is therefore
a function of the output voltage.
The board also provides the connections needed for digital communication between the ZSPM1035D 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 ZSPM8835 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.
