Applications
Distributed power architectures Intermediate bus voltage applications Servers and storage applications Network equipment PRODUCT OVERVIEW Murata Power Solutions is introducing the first in a series of digitally controlled DC-DC converters that are based on a 32-bit ARM processor. The DBE series provides a fully regulated, digitally controlled DC output in an eighth-brick format that will support the evolving, Advanced Bus Converter (ABC) industry standard footprint for isolated board mounted power modules. The DBE series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules. The DBE series products are eighth-brick DC-DC converter with a digital interface support- ing the PMBus standard for communicating with power devices. The DBE series also supports the TNV standard for input Voltage with a 36–75Vin specified Vin range and was designed to provide payload power in distributed power architectures. The DBE offers a “droop” load sharing option for paralleling modules in the most demanding, power hungry applications or to provide redundancy in high reliability applications. The converter also offers high input to output isolation of 2250 VDC as required for Power over Ethernet (PoE) applications. The DBE series is suitable for applications covering MicroTCA, servers and storage applications, networking equip- ment, Power over Ethernet (PoE), fan trays, wireless networks, wireless pre-amplifiers, industrial and test equipment along with other applications requiring a regulated 12V and 5V.

All models are specified with an external 1μF multi-layer ceramic and 10μF capacitors across their output pins. Over-current protection is non-latching with auto recovery (Hiccup) Regulation specifications describe the output voltage changes as the line voltage or load current is varied from its nominal or midpoint value to either extreme. When baseplate temperature is above the maximum operating baseplate temperature of 110°C and below thermal protection temperature of 130°C, the module will continue working but the thermal stress will be above the IPC9592 guide limit for long-term operation. It is not recommended to run in such a situation long-term.

www.murata-ps.com/support Power Management Overview The module includes a wide range of readable and configurable power manage- ment features that are easy to implement with a minimum of external components. Furthermore, the module includes protection features that continuously protect the load from damage due to unexpected system faults. The SMBALERT pin alerts the host if there is a fault in the module. The following product parameters can continuously be monitored by a host: Vout, Iout, Vin, Temperature, and Power Good. The module is distributed with a default configuration suitable for a wide range operation in terms of Vin, Vout, and load. All power management functions can be reconfigured using the PMBus interface. The product provides a PMBus digital interface that enables the user to configure many aspects of the device operation as well as monitor the input and output parameters. Please contact Murata-PS for design support of special configurations. Soft-start Power Up The default rise time of the ramp up is 20 ms. When starting by applying input voltage the control circuit boot-up time adds an additional 10 ms delay. The soft- start power up of the module can be reconfigured using the PMBus interface. Over Voltage Protection (OVP) The module includes over voltage limiting circuitry for protection of the load. The default OVP limit is 20% above the nominal output voltage. If the output voltage surpasses the OVP limit, the module can respond in different ways. The default response from an over voltage fault is to immediately shut down. The device will continuously check for the presence of the fault condition, and when the fault condition no longer exists the device will be re-enabled. The OVP fault level and fault response can be reconfigured using the PMBus interface. 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 hicup mode. The current limit could be configured by simply setting the IOUT_OC_FAULT_LIMIT to be greater than the IOUT_OC_WARN_LIMIT. The maximum value that the current limit could be set is 50A. 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. Switching Frequency Adjust Using PMBus TECHNICAL NOTES By default the switching frequency is set to 175-250 KHz variable frequency con- trol. The product is optimized at this frequency but it can be changed to 175 KHz fixed frequency control. The thermal performance can be affected if the switch- ing frequency is changed when Vin is above 50 Vdc. The following graph shows Frequency vs. Vin. PMBus Interface This module offers a PMBus digital interface that enables the user to configure many characteristics of the device operation as well as to monitor the input and output voltages, output current and device temperature. The module can be used with any standard two-wire I2C or SMBus host device. In addition, the module is compatible with PMBus version 1.2 and includes an SMBALERT line to help alleviate bandwidth limitations related to continuous fault monitoring. The module supports 100 kHz and 400 kHz bus clock frequency only. Monitoring via PMBus A system controller (host device) can monitor a wide variety of parameters through the PMBus interface. The controller can monitor fault conditions by monitoring the SMBALERT pin, which will be asserted when any number of pre-configured fault or warning conditions occur. The system controller can also continuously monitor any number of power conversion parameters including but not limited to the following:
- Input voltage
- Output voltage
- Output current
- Module temperature Software Tools for Design and Production For these modules Murata-PS provides software for configuring and monitoring via the PMBus interface.

www.murata-ps.com/support TECHNICAL NOTES (CONT.) DBE/DVE Series Up to 300W Digital Fully Regulated Intermediate DC-DC Bus Converter SDC_DBE Series.A13 Page 29 of 34 Parallel Load Sharing (S Option, Droop Load Sharing) Two or more converters may be connected in parallel at both the input and output terminals to support higher output current (total power, see figure 2) or to improve reliability due to the reduced stress that results when the modules are operat- ing below their rated limits. For applications requiring current share, followed the guidelines below. The products have a pre-configured voltage droop. The stated output voltage set point is at no load. The output voltage will decrease when the load current is increased. The voltage will drop droop 0.35V while load reaches max load. Our goal is to have each converter contribute nearly identical current into the output load under all input, environmental and load conditions. Using Parallel Connections – Load Sharing (Power Boost) Direct Connection Parallel Guidelines Use a common input power source. The input voltage must be between 36V and 75V. +Vout and –Vout of all parallel units should be connected with a balance output impedance; +Sense and –Sense should be connected together (see figure 2). Turn all units off before configuring the output voltage via PMBus commands; all units must have the same output voltage configuration. It is recommended to turn on one unit first and then turn other unit (s) on after the output for the first one has settled. Turn on the next unit (s) after the previ- ous unit reaches its regulated output voltage for at least 10mS. Users can use a different control signal to turn each unit on. Users can use a common primary Remote On/Off logic control signal to turn on modules at the same time after the input voltage rises above 36V. Do not use PMBus to control unit On/Off when parallel operation is used. First power up the parallel system (all converters) with a load not exceeding the rated load of 60%*35A*UNITS_QUANTITY and allow converters to settle (typically 10-50mS) before applying full load (90% load is recommended). If the loads are downstream POL converters, power these up shortly after the converter has reached steady state output. Also be aware of the delay caused by charging up external bypass capacitors. When converters are connected in parallel, allow for a safety factor of at least 10%. Up to 90% of max output current can be used from each module. It is critical that the PCB layout incorporates identical connections from each module to the load; use the same trace rating and airflow/thermal environments. If you add input filter components, use identical components and layout. For Power-down, do not soft-off (GUI) while in parallel operation. Power down units by primary On/Off signal. Turn units off at the same time or one by one to avoid the OCP being triggered. 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. Using Parallel Connections – Redundancy (N+1) The redundancy connections require external user supplied “OR”ing diodes or “OR”ing MOSFETs for reliability purposes. The diodes allow for an uninterruptable power system operation in case of a catastrophic failure (shorted output) by one of the converters. The diodes should be identical part numbers to enhance balance between the converters. The default factory nominal voltage should be sufficiently matched between converters. The OR’ing diode system is the responsibility of the user. Be aware of the power levels applied to the diodes and possible heat sink requirements. Schottky power diodes with approximately 0.3V drops or “OR”ing MOSFETs may be suitable in the loop whereas 0.7 V silicon power diodes may not be advisable. In the event of an internal device fault or failure of the mains power modules on the primary side, the other devices automatically take over the entire supply of the loads. In the basic N+1 power system, the “N” equals the number of modules required to fully power the system and “+1” equals one back-up module that will take over for a failed module. If the system consists of two power modules, each providing 50% of the total load power under normal operation and one module fails, another one delivers full power to the load. This means you can use smaller and less expensive power converters as the redundant elements, while achieving the goal of increased availability. Thermal Shutdown Extended operation at excessive temperature will initiate overtemperature shutdown triggered by a temperature sensor outside the PWM controller. This operates similarly to overcurrent and short circuit mode. The inception point of the overtemperature condition depends on the average power delivered, the ambient temperature and the extent of forced cooling airflow. Thermal shutdown uses only the hiccup mode (autorestart) and PMBus configurable hysteresis. Start Up Considerations When power is first applied to the DC-DC converter, there is some risk of start up 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.
