Refer to Note [3] on following page for applicable model information DSQ/DAQ/DCQ Series 600W Quarter Brick DOSA Digital PMBus Interface Murata Power Solutions is introducing the first in a series of DOSA compliant, digitally controlled DC-DC converters that are based on a 32-bit ARM proces- sor. The DSQ series provides a fully regulated, digi- tally controlled DC output in a ¼-brick format that will support the DOSA industry standard footprint for iso- lated board mounted power modules. The DSQ series supports advances in power conversion technology including a digital interface supporting the PMBus protocol for communications to power modules. The DSQ0150V2 is an isolated, regulated, 600W-12Vout quarter brick that supports the TNV (Telecommunica- tions Network Voltage) input voltage range of 36V– 75V with a typical efficiency of 96%. The DSQ series also incorporates a “droop” load sharing option that allows connecting two or more units together in par - allel for demanding power-hungry applications or to provide redundancy in high reliability applications. The converter also offers high input to output of 2250 VDC as required for Power over Ethernet (PoE) applications. The DSQ series is suitable for applications covering MicroTCA, servers and storage applications, network- ing equipment, Telecommunications equipment, Power over Ethernet (PoE), fan trays, wireless networks, wire- less pre-amplifiers, and industrial and test equipment, along with other applications requiring a regulated 12V.

www.murata-ps.com/support Power Management Overview and PMBus Interface (Applicable Models) A wide range of parameters can be read and configured by the system/host by using PMBus™ digital communications. 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 restarts when the fault condition no longer exists. 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 hiccup 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 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. 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 or to improve reliability due to the reduced stress that result when the modules are operating 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 TECHNICAL & APPLICATIONS OVERVIEW is at no load. The output voltage will decrease when the load current is increased. The voltage will drop 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. 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 uninterruptible 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. 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.

Conducted emissions performance, Negative Line, CISPR 22, Class B, full load [4] Layout Recommendations Most applications can use the filtering which is already installed inside the converter or with the addition of the recommended external capacitors. 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.
