Each module is provided pre-configured for a wide range operation. Refer to the PMBus™ Interface section for details. SMBAERT# Hardware Signal (Applicable Models) SMBALERT# signal offers an alternate method for system/host notification that a fault or Warning has been detected (mirrors the STATUS_X fault/warn register bits) within the module and is useful in applications requiring real time fault notifica- tion independent or in addition to reading PMBus™ STATUS_X register fault bits which may not be read by system/host frequently enough to detect that a fault/ warning bit flag was set. Internally driven low <0.4Vdc indicates a Vout, Iout, Vin, Temperature, or Power Good fault/warning has been detected and remains low until the fault/warning stimulus has been removed and the system/host clears the individual bit flag or issues “CLEAR_FAULTS” command. Drive high, >2.4Vdc to indicate no fault conditions within power module are detected. Soft-start Power Up The default rise time of the ramp up is 30ms. When starting by applying input volt- age the control circuit boot-up time adds an additional 10ms delay. The soft-start power up of the module can be reconfigured using the PMBus interface. Output Over Voltage Protection (OVP) Both OVP limit and response can be configured via PMBus command (See PMBus Command 40h VOUT_OV_FAULT_LIMIT for details). The default output OVP limit is set to 20% above nominal output voltage and responds by immediately shutdown of main output and occur, output is latch, to rectify the fault, need to restart enable or Vin. Over Current Protection (OCP, Current limit) The module includes current limiting circuitry for protection at continuous over load. The default setting for the product is latch mode. The current limit can be configured by PMBus command 0x46, IOUT_OC_FAULT_LIMIT, to be greater than the IOUT_OC_WARN_LIMIT (PMBus Command 0x4A). The maximum value that the current limit could be set is 40A. Power Good The module provides Power Good (PG) flag in the STATUS_WORD register that indicates the output voltage is within a specified tolerance of its target level and no fault condition exists. The Power Good pin default logic is negative and it can be configured by MFR_PGOOD_POLARITY. CAUTION: This converter is not internally fused. To avoid danger to persons or equipment and to retain safety certification, the user must connect an external fast-blow input fuse as listed in the specifications. Be sure that the PC board pad area and etch size are adequate to provide enough current so that the fuse will blow with an overload. Start Up Considerations When power is first applied to the DC-DC converter, there is some risk of startup difficulties if you do not have both low AC and DC impedance and adequate regulation of the input source. Make sure that your source supply does not allow the instantaneous input voltage to go below the minimum voltage at all times. Use a moderate size capacitor very close to the input terminals. You may need two or more parallel capacitors. A larger electrolytic or ceramic cap supplies the surge current and a smaller parallel low-ESR ceramic cap gives low AC impedance. Remember that the input current is carried both by the wiring and the ground plane return. Make sure the ground plane uses adequate thickness copper. Run additional bus wire if necessary. Input Fusing Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should also be used when there is the pos- sibility of sustained input voltage reversal which is not current-limited. For greatest safety, we recommend a fast blow fuse installed in the ungrounded input supply line.

Once operating, converters will not turn off until the input voltage drops below the Under-Voltage Shutdown Limit. Subsequent restart will not occur until the input voltage rises again above the Start-Up Threshold. This built-in hysteresis prevents any unstable on/off operation at a single input voltage. The over/under-voltage fault level and fault response and hysteresis can be configured via the PMBus interface. See commands 0x55 (VIN_OV_FAULT_LIMIT) and 0x59 (VIN_UV_FAULT_LIMIT) in the PMBus command list for additional details Start-Up Time Turn-on time (see Specifications) is the time interval between the point when the rising input voltage crosses the Start-Up Threshold and the output voltage rises to within 10% of regulation point. These converters include a soft start circuit to control Vout ramp time, thereby limiting the input inrush current. The On/Off Remote Control interval from On command to Vout (final ±10%) assumes that the converter already has its input voltage stabilized above the Start- Up Threshold before the On command. The interval is measured from the On command until the output enters and remains within its specified accuracy band. See PMBus command 0x60 (TON_DELAY) for additional configuration details Recommended Input Filtering The user must assure that the input source has low AC impedance to provide dynamic stability and that the input supply has little or no inductive content, includ- ing long distributed wiring to a remote power supply. The converter will operate with no additional external capacitance if these conditions are met. For best performance, we recommend installing a low-ESR capacitor imme- diately adjacent to the converter’s input terminals. The capacitor should be a Vin Measuring Input Ripple Current C1 = 1uF; C2 = 10uF LOAD 2-3 INCHES (51-76mm) FROM MODULE Measuring Output Ripple and Noise (PARD) ceramic type such as the Murata GRM32 series or a polymer type. More input bulk capacitance may be added in parallel (either electrolytic or tantalum) if needed. Recommended Output Filtering This series need minimum polymer capacitor to keep loop stabilization. However, the user may install external output capacitance to further improve ripple or for improved dynamic response, however low-ESR ceramic (Murata GRM32 series) or polymer capacitors must be used and mounted close to the converter using only as much capacitance as required to achieve your ripple and noise objectives. Excessive capacitance may make step load recovery sluggish and/or introduce instability. Never exceed the maximum rated output capacitance listed in the specifications. Input Ripple Current and Output Noise All models in this converter series are tested and specified for input reflected ripple current and output noise using designated external input/output components, circuits and layout as shown in the figures below. The Cbus and Lbus components simulate a typical DC voltage bus. Minimum Output Loading Requirements All models regulate within specification and are stable under no load to full load conditions. Thermal Shutdown (OTP) This series includes thermal sense and shutdown circuitry that protects itself from ov ertemperature conditions. Upon detection of overtemperature condition defined by PMBus command 0x4F “OT_FAULT_LIMIT”, the module enters OTP and shuts down. Once the temperature falls below restart threshold, as defined in PMBus command list, (OT_FAULT_LIMIT, 0x4F and MFR_OT_ FAULT_HYS, 0xEA), the module automatically restarts. OTP fault limit and recovery hysteresis are configu- rable via PMBus. CAUTION: If you operate too close to the thermal limits, the converter may shut down suddenly without warning. Be sure to thoroughly test your application to avoid unplanned thermal shutdown.

Note that these are AVERAGE measurements. The converter will accept brief increases in current or reduced airflow as long as the average is not exceeded. Note that the temperatures are of the ambient airflow, not the converter itself which is obviously running at higher temperature than the outside air. Also note that “natural convection” is defined as very flow rates which are not using fan- forced airflow. Depending on the application, “natural convection” is usually about 30-65 LFM but is not equal to still air (0 LFM). Murata Power Solutions makes Characterization measurements in a closed cycle wind tunnel with calibrated airflow. We use both thermocouples and an infrared camera system to observe thermal performance. As a practical matter, it is quite difficult to insert an anemometer to precisely measure airflow in most appli- cations. Sometimes it is possible to estimate the effective airflow if you thoroughly understand the enclosure geometry, entry/exit orifice areas and the fan flow rate specifications. CAUTION: If you exceed these Derating guidelines, the converter may have an unplanned Over Temperature shut down. Also, these graphs are all collected near Sea Level altitude. Be sure to reduce the derating for higher altitude. Output Short Circuit Condition The short circuit condition is an extension of the “Current Limiting” condition. When the monitored peak current signal reaches a certain range, the PWM controller’s outputs are shut off thereby turning the converter “off.” This is followed by an extended time out period. This period can vary depending on other conditions such as the input voltage level. Following this time out period, the PWM controller will attempt to re-start the converter by initiating a “normal start cycle” which includes soft start. If the “fault condition” persists, another “hiccup” cycle is initiated. This “cycle” can and will continue indefinitely until such time as the “fault condition” is removed, at which time the converter will resume “normal operation.” Operating in the “hiccup” mode during a fault condition is advantageous in that average input and output power levels are held low preventing excessive internal increases in temperature. Remote On/Off Control The MPQ series modules are equipped with an On/Off control pin (internal pull up, TTL open-collector and/or CMOS open-drain compatible) and is configurable via PMBus interface. Output is enabled when the On/Off is grounded or brought to within a low voltage (see specifications) with respect to –Vin. The device is off (disabled) when the On/Off is left open or is pulled high to +13.5Vdc with respect to –Vin. The On/Off function allows the module to be turned on/off by an external device switch. The restart delay for this module to turn On/Off by the On/Off control pin is 200ms. On/Off can be configured by PMBus command 0xDD (MFR_PRIMARY_ON_ OFF_ CONFIG); default configuration does not ignore the control pin and therefore requires the On/Off control pin to be asserted to start the unit. On/Off status is dependent on On/Off control and OPERATION (PMBus com- mand) status; both must be ON to turn MPQ on; if one of them is OFF, unit will be turned off. Output Capacitive Load These converters require external minimum capacitance added to achieve rated specifications. Users should consider adding capacitance to reduce switching noise and/or to handle spike current load steps. Install only enough capacitance to achieve noise objectives. Excess external capacitance may cause degraded transient response and possible oscillation or instability. Remote Sense Input Use the Sense inputs with caution. Sense is normally connected at the load. Sense inputs compensate for output voltage inaccuracy delivered at the load. This is done by correcting IR voltage drops along the output wiring and the current carrying capacity of PC board etches. This output drop (the difference between Sense and Vout when measured at the converter) should not exceed 0.5V. Consider using heavier wire if this drop is excessive. Sense inputs also improve the stability of the converter and load system by optimizing the control loop phase margin. Remote Sense Circuit Configuration

www.murata-ps.com/support MPQ600 -28V21-D48NBMC 600W RFPA Quarter Brick Digital PMBusTM Interface MPQ600-28V21-D48NBMC.A01 Page 14 of 26 Note: The Sense input and power Vout lines are internally connected through low value resistors to their respective polarities so that the converter can operate without external connection to the Sense. Nevertheless, if the Sense function is not used for remote regulation, the user should connect +Sense to +Vout and – Sense to –Vout at the converter pins. The remote Sense lines carry very little current. They are also capacitively cou- pled to the output lines and therefore are in the feedback control loop to regulate and stabilize the output. As such, they are not low impedance inputs and must be treated with care in PC board layouts. Sense lines on the PCB should run adjacent to DC signals, preferably Ground. In cables and discrete wiring, use twisted pair, shielded tubing or similar techniques. Any long, distributed wiring and/or significant inductance introduced into the Sense control loop can adversely affect overall system stability. If in doubt, test your applications by observing the converter’s output transient response during step loads. There should not be any appreciable ringing or oscillation. You may also adjust the output trim slightly to compensate for voltage loss in any external filter elements. Do not exceed maximum power ratings. Please observe Sense inputs tolerance to avoid improper operation: [Vout(+) −Vout(-)] − [Sense(+) −Sense(-)] ≤ 10% of Vout Output overvoltage protection is monitored at the output voltage pin, not the Sense pin. Therefore, excessive voltage differences between Vout and Sense together with trim adjustment of the output can cause the overvoltage protection circuit to activate and shut down the output. Power derating of the converter is based on the combination of maximum output current and the highest output voltage. Therefore, the designer must ensure: (Vout at pins) x (Iout) ≤ (Max. rated output power) Soldering Guidelines Murata Power Solutions recommends the specifications below when install- ing these converters. These specifications vary depending on the solder type. Exceeding these specifications may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C for 30 minutes). Your production environment may differ; therefore, please thoroughly review these guidelines with your process engineers. Wave Solder Operation for Through-Hole Mounted Products (THMT) For Sn/Ag/Cu based solders: Maximum Preheat Temperature 115 Maximum Pot Temperature 270 Maximum Solder Dwell Time 7 seconds For Sn/Pb based solders: Maximum Preheat Temperature 105 Maximum Pot Temperature 250 Maximum Solder Dwell Time 6 seconds Trimming the Output Voltage The Trim input pin is used to adjust the output voltage over the rated trim range (please refer to the Specifications). As illustrated in the trim equations and circuit diagrams below, trim adjustments use a single fixed resistor connected between the Trim input and either Vout Sense pin. Trimming resistors should have a low temperature coefficient (±100 ppm/deg.C or less) and be mounted close to the c onverter keeping leads short. If the trim function is not used, leave the trim unconnected, the converter will default to its specified output voltage accuracy. CAUTION: 1. Avoid activating shutdown protection (OVP, OCP, OTP) by ensuring the output voltage or output power is not exceeded when setting the output voltage trim. 2. Keep the trim external connections as short as possible to avoid excessive noise that may otherwise cause instability or oscillation using shielding if needed. Trim Equations Trim Up: Connect Trim (Pin #J6) to +Vout Sense (Pin #J7) Rt up(kΩ) = 1*Vonom*(1+Δ)/(1.225*Δ)-1/Δ-2 Δ=|(Vonom-Vo)/Vonom| Trim Down: Connect Trim (Pin #J6) to -Vout Sense (Pin #J5) Rt down (kΩ) =1/((Vonom-Vo)/Vonom)-2 NOTE: Adjustment accuracy is subject to resistor tolerances and factory-adjusted output accuracy. Mount trim resistor close to converter. Use short leads. LOAD R TRIM DOWN –VOUT –VIN TRIM -SENSE ON/OFF CONTROL +SENSE +VIN +VOUT

For greater emissions suppression, consider additional filter components and/or shielding. Emissions performance will depend on the user’s PC board layout, the chassis shielding environment and choice of external components. Since many factors affect both the amplitude and spectra of emissions, we recommend using an engineer who is experienced at emissions suppression.

Both longitudinal and transverse airflow studies are possible by rotation of this carrier board since there are often significant differences in the heat dissipa- tion in the two airflow directions. The combination of adjustable airflow, adjustable ambient heat, and adjustable Input/Output currents and voltages mean that a very wide range of measure- ment conditions can be studied. The collimator reduces the amount of turbulence adjacent to the UUT by minimizing airflow turbulence. Such turbulence influences the effective heat transfer characteristics and gives false readings. Excess turbulence removes more heat from some surfaces and less heat from others, possibly causing uneven overheating. Both sides of the UUT are studied since there are different ther- mal gradients on each side. The adjustable heating element and fan, Vertical Wind Tunnel built-in temperature gauges, and no-contact IR camera mean that power supplies are tested in real-world conditions.
