Jumper pins J1 and J2 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 J1 and/or J2 (white arrows on the board
indicate pin 1; see section 4.3). 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 center pin on J1 or J2 can be used as a trigger for an oscilloscope.
Jumper J7 can be used to select the amount of capacitance connected to the output of the ZSPM9060 (see
section 4.2).
The J5 DIP switch must be set to the proper compensation scheme. Further details are provided in section 4.2.
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’s transient response.

DC power supply: An external power supply is required for the ZSPM15xx Evaluation Board. Its output
voltage should be at least 12V with a rated output current of approximately 1A to 8A depending on the test
conditions.
Electronic load: An external DC load is highly recommended as the Evaluation Board features only
transient loads due to constraints on power dissipation. While an electronic load can be very advantageous,
load resistors could also be sufficient for testing. Ensure that the electronic load has an adequate power
rating.
Oscilloscope: Connecting an oscilloscope to the Evaluation Kit is strongly recommended for measuring
the performance of the Evaluation Board in the time domain. The Evaluation Board features an SMB
connector connected to the output of the power stage for easy connection to an oscilloscope.
Evaluation Kit Setup
This section covers the steps for powering up the ZSPM15xx 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 this step-by-step instruction to power up the ZSPM15xx Evaluation Board:
Step 1: 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.
Step 2: 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 ZSPM15xx
Evaluation Board.
Step 3: The power-good (PG) LED on the board should be on now (see Figure 2.1) and a voltage consistent
with the preconfigured output voltage for ZSPM15xx product number (see section Table 5.2 should be
present on the output terminals.

Evaluation Board Hardware and Software Setup
Introduction
The ZSPM15xx is a fixed output voltage controller that is pre-configured with settings determined by the
ZSPM15xx product number.
The output voltage is set as part of the configuration data. For output voltages up to 1.2V, the controller is
configured to operate without a feedback divider. For output voltages above 1.2V, the controller is configured to
operate with a feedback divider. Refer to the bill of materials (BOM) for the specific ZSPM15xx product number
given in Table 5.2 for detailed information about the output voltage feedback divider.
The ZSPM15xx has four pre-configured compensators. The four compensators have been optimized for specific
ranges of output capacitors. Section 4.2 describes how the Evaluation Board can be configured for any of the four
options for output capacitor ranges, allowing simple comparisons of the dynamic performance of the complete
solution. The output capacitor range can be selected on header J7 (see section 4.2). The ZSPM15xx Data Sheet
provides further information about the compensation loop configuration of the ZSPM15xx controller and typical
performance measurements.
4.2.
Output Capacitor Range Selection
The ZSPM15xx controller can be configured with one of four sets of compensation loop parameters. Each set of
compensation parameters has been designed to match a range of output capacitors (see the ZSPM15xx Data
Sheet for more information on the output capacitor ranges and compensation loop settings). The ZSPM15xx
Evaluation Board allows the user to test the performance of the controller for each of the four output capacitor
ranges. In the final application, the set of compensation parameters would be selected via a pin-strapping resistor
as described in the data sheet.
A minimum number of ceramic capacitors are always connected to the output of the ZSPM9060 (capacitor range
#1, selected if there is no jumper on J7) and further capacitor banks can be selected with a jumper on header J7
(see Table 4.1). On the Evaluation Board, one of the three LEDs adjacent to J7 will turn green to indicate if
capacitor range #2, #3, or #4 has been selected (see Figure 2.1). If none of the LEDs are on, it means that
capacitor range #1 has been selected.
Figure 4.1 J7 – Output Capacitor Range Hardware Selection
Important: For the output capacitor range selected by J7, a corresponding setting on the J5 DIP switch must be
made as shown in Table 4.1 to select the ZSPM15xx compensation loop configuration (Comp0, Comp1, Comp2,
or Comp3) optimized for the selected output capacitors.

For both J7 and the J5 DIP switch, the settings must be made one-at-a-time. Do not place more than one jumper on J7
at a time. Do not set more than one position to ON in the group of four settings on the right of the DIP switch or in the
group of four settings on the left.
** The first four settings of the J5 DIP switch (indicated with x) are for selecting the over-current protection threshold, for
which the settings are given in section 4.4. For this step, this first set of switches can be considered “do not care,”
except that no more than one switch in this group can be set to ON at a time.
There is a provision on right side of the DIP switch for adding a jumper and a potentiometer or fixed resistor for
selecting one of seven slew rate settings. For each set of compensation loop parameters, there is a choice of
seven slew rates for the output voltage during power-up. The selection of the slew rate can be used to limit the
input current of the DC/DC converter while it is ramping up the output voltage. The current needed to charge the
output capacitors increases in direct proportion to the slew rate. See the ZSPM15xx Data Sheet for further details.

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 from the power supply to the ZSPM15xx Evaluation Board is OFF.
2. Select the ZSPM15xx output capacitor range via header J7 and set the corresponding position on the J5
DIP switch per Table 4.1.
3. Apply the input voltage to the ZSPM15xx Evaluation Board.
4. Measure the dynamic performance with an oscilloscope using either the on-board transient loads (see
section 4.3) or an external electronic load.
4.3.
On Board Transient Loads
The ZSPM15xx Evaluation Board has on-board transient loads that can be used to test the dynamic performance
of the ZSPM15xx 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 ZSPM9060. A schematic
of the transient load circuitry is provided in Appendix B.
There are two transient loads that can be enabled via headers J1 and J2 respectively (see Figure 4.2). The two
loads can be enabled simultaneously to achieve a larger current step. The timing signal for the transient loads has
an ON time of approximately 1 millisecond with a time period of approximately 80 milliseconds (see Figure 4.3).

Setting the Over Current Protection (OCP)
The ZSPM15xx-KIT01 can be configured to support a wide range of different over-current protection (OCP)
thresholds based on the user’s selection for the inductor. The voltage between the ISNSP and ISNSN pins
triggers the OCP protection. This voltage represents the over-current threshold because faults are detected by
measuring the voltage across the DCR of the selected inductor. Table 4.2 lists the different configuration options
for selecting the OCP voltage threshold via the total resistance connected to the CONFIG0 pin on the ZSPM15xx.
The ZSPM15xx-KIT01 has the four preset current limit settings given in Table 4.3, which correspond to the index
settings shaded pink in Table 4.2. If no preset is selected, the current limit is set to index 29 (70.0mV.) The
presets can be selected with positions 1 through 4 on the J5 DIP switch (see Figure 4.4). There is provision on left
side of the J5 DIP switch for the footprints for jumper J8 and potentiometer RP2 or fixed resistor R17 (on the back
of the board) for achieving custom OCP settings. When RP2 or R17 is used, the J8 jumper must be shorted.

ZSPM15xx-KIT01
Evaluation Kit for the ZSPM15xx True-Digital PWM Controller
Selecting a custom OCP resistor is a simple calculation. For example, for a design with a maximum current of
20A and an inductor with 2mΩ resistance (DCR), the OCP can be calculated with the following equation:
20A x 1.25 (25% current limit buffer) x 0.002Ω = 50mV
Next select the resistor from Table 4.2 that correlates with an over-current threshold voltage of 50mV, which is
15.8kΩ (index 25). For more details, see the ZSPM15xx Data Sheet.
Note: Due to the temperature compensation feature, the ZSPM15xx over-current threshold should be based on
the current sense signal at 25°C. Temperature drift is automatically compensated within the ZSPM15xx.
Recommendation: For the selection of the over-current threshold voltage, include the tolerance of the inductor’s
DCR and take the parasitic effects of the circuit board layout into account.
