ZSPM1035C / ZSPM1035D
True Digital PWM Controller (Single-Phase, Single-Rail)

Product Summary
2.1. Overview
The ZSPM1035C and ZSPM1035D are true-digital single-phase PWM controllers optimally configured for use
with the Murata Power Solutions 35A Power Block OKLP-X/35-W12-C in smart digital power solutions. The
ZSPM1035C/D has a digital power control loop incorporating output voltage sensing, average inductor current
sensing, and extensive fault monitoring and handling features. Several different functional units are integrated in
the device. A dedicated digital control loop is used to provide fast loop response and optimal output voltage
regulation. This includes output voltage sensing, average inductor current sensing, a digital control law, and a
digital pulse-width modulator (DPWM). In parallel, a dedicated error handler allows fast and flexible detection of
error signals and their appropriate handling. A housekeeping analog-to-digital converter (HKADC) ensures the
reliable and efficient measurement of environmental signals, such as input voltage and temperature.
An application-specific, low-energy integrated microcontroller is used to control the overall system. It manages
configuration of the various logic units according to the preprogrammed configuration look-up tables and the
external configuration resistors connected to the CONFIG0 and CONFIG1 pins. These pin-strapping resistors
expedite configuration of output voltage, compensation, and rise time without requiring digital communication.
ZMDI’s Pink Power Designer™ graphical user interface (GUI) allows the user to monitor the controller’s
measurements of the environmental signals and the status of the error handler via the GPIO2 and GPIO3 pins.

Functional Description
3.1. Power Supply Circuitry, Reference Decoupling, and Grounding
The ZSPM1035C/D incorporates several internal power regulators in order to derive all required supply and bias
voltages from a single external supply voltage. This supply voltage can be either 5V or 3.3V depending on
whether the internal 3.3V regulator should be used. If the internal 3.3V regulator is not used, 3.3V must be
supplied to the 3.3V and 5V supply pins. Decoupling capacitors are required at the VDD33, VDD18, and AVDD18
pins (1.0µF minimum; 4.7µF recommended). If the 5.0V supply voltage is used, i.e., the internal 3.3V regulator is
used, a small load current can be drawn from the VDD33 pin. This can be used to supply pull-up resistors for
example.
The reference voltages required for the analog-to-digital converters are generated within the ZSPM1035C/D.
External decoupling must be provided between the VREFP and ADCVREF pins. Therefore, a 4.7µF capacitor is
required at the VREFP pin, and a 100nF capacitor is required at the ADCVREF pin. The two pins should be
connected with approximately 50Ω resistance in order to provide sufficient decoupling between the pins.
Three different ground connections (the pad, AGND pin, and GND pin) are available on the outside of the
package. These should be connected together to a single ground tie. A differentiation between analog and digital
ground is not required.

ZSPM1035C / ZSPM1035D
True Digital PWM Controller (Single-Phase, Single-Rail)
3.2. Reset/Start-up Behavior
The ZSPM1035C/D employs an internal power-on-reset (POR) circuit to ensure proper start up and shut down
with a changing supply voltage. Once the supply voltage increases above the POR threshold voltage (refer to
section 1.3), the ZSPM1035C/D begins the internal start-up process. Upon its completion, the device is ready for
operation.
3.3. Digital Power Control
3.3.1.
Overview
The digital power control loop consists of the integral parts required for the control functionality of the
ZSPM1035C/D. A high-speed analog front-end is used to digitize the output voltage. A digital control core uses
the acquired information to provide duty-cycle information to the PWM that controls the drive signals to the power
stage.
3.3.2.
Output Voltage Feedback
The voltage feedback signal is sampled with a high-speed analog front-end. The feedback voltage is differentially
measured and subtracted from the voltage reference provided by a reference digital-to-analog converter (DAC)
using an error amplifier. A flash ADC is then used to convert the voltage into its digital equivalent. This is followed
by internal digital filtering to improve the system’s noise rejection.
3.3.2.1. ZSPM1035C
The ZSPM1035C has been designed for an output voltage range from 0.62 to 1.20V. The VFBP pin should be
connected to the converter output through a 1.75kΩ resistor, and a small filter capacitor, typically 22pF, should be
connected between the VFBP and VFBN pins of the ZSPM1035C.
3.3.2.2. ZSPM1035D
The ZSPM1035D has been designed for an output voltage range from 1.25 to 3.40V. An external feedback divider
is required for the ZSPM1035D. The VFBP pin should be connected to the converter output through a 1.75kΩ
resistor, and a 1kΩ resistor should be connected between the VFBP and VFBN pin of the ZSPM1035D. A small
filter capacitor, typically 22pF, should also be connected between the VFBP and VFBN pins of the ZSPM1035D.
3.3.3.
Digital Compensator
The sampled output voltage is processed by a digital control loop in order to modulate the DPWM output signals
controlling the power stage. This digital control loop works as a voltage-mode controller using a PID-type
compensation. The basic structure of the controller is shown in Figure 3.1. The proprietary State-Law™ Control
(SLC) concept features two parallel compensators, steady-state operation, and fast transient operation. The
ZSPM1035C/D implements fast, reliable switching between the different compensation modes in order to ensure
good transient performance and quiet steady state. This has been utilized to tune the compensators individually
for the respective needs; i.e., quiet steady-state and fast transient performance.

True Digital PWM Controller (Single-Phase, Single-Rail)
Figure 3.1
Simplified Block Diagram for the Digital Compensation
Three different techniques are used to improve transient performance further:
•
•
•
Tru-sample Technology™ is used to acquire fast, accurate, and continuous information about the output vol-
tage so that the device can react quickly to any change in output voltage. Tru-sample Technology™ reduces
phase-lag caused by sampling delays, reduces noise sensitivity, and improves transient performance.
The Sub-cycle Response™ (SCR) technique, a method to drive the DPWM asynchronously during load tran-
sients, allows limiting the maximum deviation of the output voltage and recharging the output capacitors
faster.
A nonlinear gain adjustment is used during large load transients to boost the loop gain and reduce the
settling time.
3.3.4.
Power Sequencing and the CONTROL Pin
The ZSPM1035C/D has a set of pre-configured power-sequencing features. The typical sequence of events is
shown in Figure 3.2. The individual values for the delay, ramp time, and post ramp time are listed in Table 3.1.
Note that the device is slew-rate controlled for ramping. Hence, when pin-strapping options for the output voltage
are used, the ramp time can change based on the configured slew-rate and the actual selected output voltage.
The slew rate can be selected in the application circuit using the pin-strap options as explained in section 4.1.
The CONTROL pin is pre-configured for active high operation.
The ZSPM1035C/D features a power good (PGOOD) output, which can be used to indicate the state of the power
rail. If the output voltage level is above the power good ON threshold, the pin is set to active, indicating a stable
output voltage on the rail. The thresholds for the power good output turn-on and turn-off are listed in Table 3.2.
Note that the power good thresholds are stored in the device as factors relative to the nominal output voltage.
Hence, using the strapping options (see section 4.1) to change the output voltage level also changes the PGOOD
thresholds.

3.3.5.
Pre-biased Start-up and Soft-Off
Dedicated pre-biased start-up logic ensures proper start-up of the power converter when the output capacitors are
pre-charged to a non-zero output voltage. Closed-loop stability is ensured during this phase.
When the DC/DC converter output is disabled, i.e. when the CONTROL pin is set low, the ZSPM1035C/D will
execute the soft-off sequence. The soft-off sequence will ramp down the output voltage to 0V and set the PWM
output in a tri-state condition.
3.3.6.
Current Sensing
The ZSPM1035C/D offers cycle-by-cycle average current sensing and over-current protection. A dedicated ADC
is used to provide fast and accurate current information over the switching period. The acquired information is
compared with the pre-configured over-current threshold to trigger an over-current fault event. DCR current
sensing across the inductor on the Murata OKLP-X/35-W12-C is supported. Additionally, the device uses DCR
temperature compensation via the external temperature sense element. This increases the accuracy of the
current sense method by counteracting the significant change of the DCR over temperature.
The schematic of the required current sensing circuitry is shown in Figure 3.3 for the widely-used DCR current-
sensing method, which uses the parasitic resistance of the inductor to acquire the current information. The
principle is based on a matched time-constant between the inductor and the low-pass filter built from a 2.15kΩ
resistor mounted on the Murata OKLP-X/35-W12-C Power Block and C8. Resistor R6 should be a precision
2.15kΩ resistor in order to provide good DC voltage rejection, .i.e. reduce the influence of the output voltage level
on the current measurement.

ZSPM1035C / ZSPM1035D
True Digital PWM Controller (Single-Phase, Single-Rail)
To improve the accuracy of the current measurement, which can be adversely affected by the temperature
coefficient of the inductor’s DCR, the ZSPM1035C/D features temperature compensation via the external
temperature sensing. The temperature of the inductor can be measured with an external temperature sense
element placed close to the inductor. This information is used to adapt the gain of the current sense path to
compensate for the increase in actual DCR.
3.3.7.
Temperature Measurement
The ZSPM1035C/D features two independent temperature measurement units. The internal temperature sensing
measures the temperature inside the IC; the external temperature sensing element is placed on the Murata
OKLP-X/35-W12-C Power Block. The ZSPM1035C/D drives 60µA into the external temperature sensing element
and measures the voltage on the TEMP pin.
3.4. Fault Monitoring and Response Generation
The ZSPM1035C/D monitors various signals for possible fault conditions during operation. The fault thresholds of
the ZSPM1035C/D controllers are given in Table 3.3.

* Nominal VOUT is selected by the pin-strap resistor on the CONFIG0 pin.
The controller fault handling will infinitely try to restart the converter on a fault condition. In analog controllers, this
infinite re-try feature is also known as “hiccup mode.”
3.4.1.
Output Over/Under Voltage
To prevent damage to the load, the ZSPM1035C/D utilizes an output over-voltage protection circuit. The voltage
at VFBP is continuously compared with a configurable threshold using a high-speed analog comparator. If the
voltage exceeds the configured threshold, the fault response is generated and the PWM output is set to low.
The ZSPM1035C/D also monitors the output voltage with a lower threshold. If the output voltage falls below the
under-voltage fault level, a fault event is generated and the PWM output is set to low.
Note that the fault thresholds are stored in the ZSPM1035C/D as factors relative to the nominal output voltage.
Hence, using the strapping options (see section 4.1) to change the output voltage level, also changes the fault
thresholds.

The ZSPM1035C/D continuously monitors the average inductor current and utilizes this information to protect the
power supply against excessive output current.
3.4.3.
Over-Temperature Protection
The ZSPM1035C/D monitors internal and external temperature. For the temperature fault conditions a soft-off
sequence is started. The soft-off sequence will ramp down the output voltage to 0V and set the PWM output in a
tri-state condition.
3.5. Monitoring and Debugging via I2C™
The Pink Power Designer™ GUI can be used to monitor the internal measurement signals of the ZSPM1035C/D
during the development phase. The status of the internal fault handler can also be monitored within the Pink
Power Designer™ GUI.
The Pink Power Designer™ GUI communicates with the ZSPM1035C/D via an I2C™* interface in which the SCL
signal is connected to the GPIO3 pin and the SDA signal is connected to the GPIO2 pin.
* I2C™ is a trademark of NXP.

4.2. Pin Strap Options of the ZSPM1035C/D
The ZSPM1035C/D provides two pin-strap configuration pins. The CONFIG0 pin is used to select the nominal
output voltage of the non-isolated DC/DC converter. The CONFIG1 pin is used to select a set of compensation
loop parameters in combination with the slew rate for the output voltage during the power-up sequence. There are
four sets of compensation loop parameters that have been optimized for different ranges of output capacitance.
The CONFIG0 and CONFIG1 pins are used to determine the index of the selected values using the resistor
values listed in Table 4.2. Each pin provides 30 configuration indexes based on resistor values from the E96
series. A resistor variation of ~2% is taken into account for initial tolerance and temperature dependency. The
values are read during the initialization phase after a POR event and are then used to look up the selected index
from the pre-configured look-up tables. Based on the index read by the ZSPM1035C/D, the controller will load the
corresponding configuration from the OTP memory of the device.

CONFIG0 – Output Voltage
The nominal output voltage of the ZSPM1035C/D is set with a pin-strap resistor on the CONFIG0 pin. The
selectable output voltages and the corresponding pin-strap resistor index are given in Table 4.3.
The nominal output voltage set points given for the ZSPM1035C are valid without an output voltage feedback
divider. To achieve optimal performance the low pass filter consisting of resistor R5 and C7 (see Figure 4.1)
should be included in the application circuit.
The nominal output voltage set points given for the ZSPM1035D are only valid if the resistors in the output voltage
feedback divider, R4 and R5 (see Figure 4.2), have the resistances specified in Table 4.1.

CONFIG1 – Compensation Loop and Output Voltage Slew Rate
The ZSPM1035C/D controllers can be configured to operate over a wide range of output capacitance. Four
ranges of output capacitance have been specified to match typical customer requirements (see Table 4.4).
Typical performance measurements for both load transient performance and open-loop Bode plots can be found
in section 4.3. Using less output capacitance than the minimum capacitance given in Table 4.4 is not
recommended.

To get the optimal performance for a given output capacitor range, one of four sets of compensation loop
parameters, Comp0 to Comp3, should be selected with a resistor between CONFIG1 and GND. The
compensation loop parameters have been configured to ensure optimal transient performance and good control
loop stability margins.
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.
Table 4.5 gives a complete list of the selectable compensation loop parameters and slew rates together with the
equivalent pin-strap resistor values.

True Digital PWM Controller (Single-Phase, Single-Rail)
4.3. Typical Performance Measurements for the ZSPM1035C and ZSPM1035D
The pre-programmed compensation loop parameters for the ZSPM1035C and ZSPM1035D have been designed
to ensure stability and optimal transient performance for the OKLP-X/35-W12-C Power Block from Murata in
combination with one of the four output capacitor ranges (see Table 4.4).
Load transient performance measurements and open-loop Bode plots for the ZSPM1035C can be found in
sections 4.3.1 to 4.3.4. The transient load steps have been generated with a load resistor and a power MOSFET
located on the same circuit board as the ZSPM1035C and the Murata OKLP-X/35-W12-C Power Block. The
ZSPM8735-KIT evaluation kit can be used to further evaluate the performance of the ZSPM1035C for the four
output capacitor ranges.
Load transient performance measurements and open-loop Bode plots for the ZSPM1035D are shown in sections
4.3.5 to 4.3.8. The transient load steps have been generated with a load resistor and a power MOSFET located
on the same circuit board as the ZSPM1035D and the Murata OKLP-X/35-W12-C Power Block. The ZSPM8835-
KIT evaluation kit can be used to further evaluate the performance of the ZSPM1035D for the four output
capacitor ranges.
