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.

Notes:

Jumper pins J100 and J101 are used to connect the onboard load transient found on the back of the board. The user
can achieve transient load steps by placing a jumper across pins 2 and 3 on J100 and/or J101 (white arrows on the
board indicate pin 1). Power resistors in series with the power MOSFETs are used as loads for the load steps, and the
current level is therefore output voltage dependent. The load resistors will draw 4.17A (J101) and 8.33A (J100) at the
nominal output voltage of 1.5V. Refer to section 6.4 for more information on the transient load circuit and important
warnings.


Jumper J104 is a test point for the load step (can be used as a trigger for an oscilloscope).
J105 is a DIP switch used to select configuration resistors for the CONFIG0 and CONFIG1 pins. Ensure that only one
switch is on in the set of switches 1 to 4 and only one switch is on in the set of switches 5 to 8.
Jumper J106 can be used to select the amount of capacitance connected to the output of the Murata OKLP-X/35-W12C Power Block. Further details are provided in section 6.3.


The SMB connector on the right side of the board is intended for connection to an oscilloscope to provide a low-noise
measurement of the output voltage.

Evaluation Kit Setup for a 1.5V Output Voltage
This section covers the steps for powering up the ZSPM8835 Evaluation Kit for the first time.
Important Safety Warning: The following procedures can result in high currents, which can
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 ZSPM8835 Evaluation Board:
Step 1: Set switches 1 and 5 on DIP switch J105 to ON and ensure that no jumper is placed on header J106.
The remainder of the switches must be in the OFF position. This selects the standard configuration for
the ZSPM8835 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 J103 with the orientation shown in

Step 4: Set the power supply voltage to 12V and enable the output of the power supply. If the power supply has
no enable button ensure that the output voltage is set to 12V before connecting it to the ZSPM8835
Evaluation Board. The Pink Power Designer™ GUI will now recognize the ZSPM1035D and show the
device in the status panel on the left side of the screen.
Note: Because the ZSPM1035D has not yet been enabled by the GUI, there should be no voltage
present on the output connectors of the ZSPM8835 Evaluation Board at this time.
Step 5: Ensure that monitoring of the input voltage, output voltage, output current, and the readings of internal
and external temperature is active. The virtual LED next to the “Monitor” button will be green when
monitoring is enabled (see Figure 5.2). Click on the “Monitor” button to enable monitoring if the virtual
LED is not green.
Step 6: Click on the “Control Pin” button located in the “Startup” subsection to enable the output of the
ZSPM8835 Evaluation Board. The power-good (PG) LED on the board should be on now (shown in
Figure 2.1), and a voltage of 1.5V should be present on the output terminals.

Evaluation Board Hardware Setup
6.1.
Introduction
The ZSPM1035D PWM controller has two configuration pins that support pin-strapping of the following parameters:

Output Voltage, VOUT

Compensation Loop Parameters

Output Voltage Slew Rate (this parameter is permanently preconfigured to be 10 V/ms on the Evaluation Board)
The output voltage is set with a pin-strap resistor between the CONFIG0 pin and the AGND pin of the
ZSPM1035D that is selected with the J105 DIP switch. Refer to section 6.2 for more information on the output
voltage selection on the ZSPM8835 Evaluation Board. The ZSPM1035D Data Sheet provides detailed information
about the output voltage selection of the ZSPM1035D.
The ZSPM1035D has four pre-configured compensators that are selectable with a pin-strap resistor between the
CONFIG1 pin and AGND that is selected with the J105 DIP switch. The four compensators have been designed
to work for specific ranges of output capacitors. Section 6.3 describes how the Evaluation Board can be
configured for any of the four capacitor ranges, thereby enabling simple comparisons of the dynamic performance
of the complete solution. The ZSPM1035D Data Sheet provides further information about the compensation loop
configurations of the ZSPM1035D controller and typical performance measurements.
6.2.
Output Voltage Selection
The ZSPM1035D has been pre-configured for 30 different output voltages (see the ZSPM1035D Data Sheet)
selectable by a pin-strap resistor between the CONFIG0 pin and AGND. Four common output voltages can be
selected with DIP switch J105 on the ZSPM8835 Evaluation Board.
Important: Ensure that for the set of switches 1 through 4 on DIP switch J105, only one switch is in the ON
position.

Follow these steps to change the output voltage:
1. Ensure that the input voltage for the ZSPM8835 Evaluation Board is OFF.
2. Select the nominal output voltage by setting the DIP switch corresponding to the required output voltage
to the “ON” position. Make sure the three remaining DIP switches are in the “OFF” position.
3. Apply the input voltage to the ZSPM8835 Evaluation Board.
4. Enable the output voltage by clicking the “Control Pin” button in the Pink Power Designer GUI™.

6.3.
Output Capacitor Range Selection
The ZSPM1035D controllers have been pre-configured with four sets of compensation loop parameters. Each set
of compensation parameters has been designed to match a range of output capacitors (see the ZSPM1035D
Data Sheet for more information on the output capacitor ranges). The Evaluation Board enables the customer to
test the performance of the controller for each of the four output capacitor ranges. A minimum set of ceramic
capacitors are always present on the output of the Murata OKLP-X/35-W12-C Power Block (capacitor range #1,
no jumper on J106) and further capacitor banks can be selected with a jumper on header J106 (see Table 6.2).
The type and number of capacitors connected to the output for each range are listed in Table 6.2. On the
Evaluation Board, one of the three LEDs adjacent to J106 will turn green to indicate if capacitor range #2, #3, or
#4 has been selected (see Figure 6.1). If none of the LEDs is on, it means that capacitor range #1 has been
selected.
Figure 6.1
J106 - Output Capacitor Range Hardware Selection
It is important to ensure that the output capacitor range selected on J106 matches the compensator selected for
the ZSPM1035D. The compensator can be selected on the J105 DIP switch with switches 5 through 8 (see Table
6.2).
Important: Ensure that for the set of switches 5 through 8 on DIP switch J105, only one switch is in the ON
position.
The output voltage slew rate is always set to 10 V/ms on the ZSPM8835 Evaluation Board.

Output Capacitor Range Test Procedure
To test the performance of the four selectable compensators, follow these simple steps:
1. Make sure that the input voltage for the ZSPM8835 Evaluation Board is OFF.
2. Select the output capacitor range via header J106.
3. Select the compensator matching the output capacitor range using positions 5 through 8 on the J105 DIP
switch.
4. Select the nominal output voltage on using positions 1 through 4 on the J105 DIP switch.
5. Apply the input voltage to the ZSPM8835 Evaluation Board.
6. Enable the output voltage by clicking the “Control Pin” in the Pink Power Designer GUI™.
7. Test the dynamic performance using either the on-board transient loads or an external electronic load.
6.4.
On-Board Transient Loads
The ZSPM8835 Evaluation Board has on-board transient loads that can be used to test the dynamic performance
of the ZSPM1035D controller. The transient loads consist of a simple timer circuit driving a power MOSFET.
The power MOSFET is connected in series with resistors connected across the output of the Murata OKLP-X/35W12-C Power Block. A schematic of the transient load circuitry is provided in Appendix B.
There are two transient loads that can be enabled on headers J100 and J101 (see Figure 6.2). The timing signal
for the transient loads has an ON time of approximately 1 millisecond with a time period of approximately 80
milliseconds as demonstrated in Figure 6.3.

ZSPM8835-KIT
Evaluation Kit for the ZSPM1035D Controller
Important: The load current is a function of the nominal output voltage set on DIP switch J105 and the resistance
of the transient load. Be sure to calculate the expected load current before enabling the transient loads. Enabling
both loads at the same time by placing jumpers across both J101 and J100 creates a load resistance of 0.12Ω,
