D1U54P-12-CONC

D1U54P-12-CONC ACAN-64 Connector Card Application Note OVERVIEW The D1U54P-12-CONC (4407001-1) interface connector card is a dual card that is intended to interconnect the output voltages and signals of two D1U54x Series power modules for laboratory/bench level evaluation of the product. The outputs are capable of being parallel connected and a common ISHARE bus is provided to ensure that both power modules share current within specified limits. The Interface Card is capable of operation from standby voltages of 3.3V, 5V and 12V (provided by the D1U54x variant under test) without any reconfiguration. It is designed and intended to be used for the members within the following series (both AC and DC input source variants and both airflow options): 3.3VSTANDBY 5VSTANDBY 12VSTANDBY MODEL VARIANTS Output Output Output HB3xC D1U54x-x-650-12-HBxxC-xxx N/A N/A HB4xC HC3PC HA3PxC D1U54x-x-1200-12-HxxxxC N/A HC4PC HA4PxC HC3C HA3C D1U54x-x-1500-12-HxxxC HB4xC HC4C HA4C End Users can also use this card in their applications as an alternative to a host system power/mid or interposer plane (consult Murata Sales for details). SAFETY PRECAUTION The D1U54P-12-CONC output connector card is intended to facilitate the connection of the output supply rails of the power module. As such there a high energy source exposed on the output connector card; please take the necessary safety precautions during the use of this connector card for product evaluation.

The Interface Connector card is basically two identical circuits provided on a single card (PCB). Each “half” has all the necessary configuration links duplicated to enable each “half” to operate individually if required. Common connections exist these being as follows: a. Power bus bars that are intended to interconnect the main 12VDC outputs of each “half”; these can be removed as required, and substituted with separate cables to the required load. b. ISHARE signal bus between each “half”. This interconnection is provided by a single jumper JP15 and can be removed if operation as two independent (no parallel connection) is required. Note that no physical parallel connection is provided to interconnect the VSTANDBY output of each “half”. If required cable connections can be provided by the End User (note: parallel connection of the VSTANDBY is subject to the limitations as described in the respective product datasheets). 2. To configure each “half” for independent or parallel operation, ensure that the following configurable jumpers (headers) have shorting links (shunts Dual Beam; TE Connectivity Pt# 390088-2) fitted across their respective Pins 1 & 2 (refer to schematic & photograph): a. JP1/JP21; +12VSENSE local voltage sense selection; deselect if remote sense connection is provided to the load. b. JP2/JP22; +12VSENSE_RTN local voltage sense selection;deselect if remote sense connection is provided to the load. c. JP11 & JP31 (PS_KILL connection to GNDB/GNDD return ; enables output. d. JP15; this jumper interconencts the ISHARE signals between the two power modules. Fit the shorting link across Pins 1 & 2 if the units are to be operated in parallel to share a common load. Remove the shorting link if the units are to be operated “independently” as separate power modules. 3. The two DC Main 12V DC outputs are interconnected with bus bars. 4. The BNC connectors for ripple & noise measurements of 12VSTBY (J7 bias/standby) and 12VOUT (J6 Main output) are intended for direct (BNC to BNC) connection (or via a 10X probe if required) to an oscilloscope. Note also that the measurement node is filtered with a parallel connected 10µF tantalum and 1µF ceramic capacitor (across tip to ground) A short 50ohm coaxial cable connnection shall be provided between the relevant BNC measurement connector and the input to the measuring ‘scope (the ‘scope bandwidth shall be limited to 20MHz). 5. Connector J8 is a PMBob I2C/SPI interface connector. The PMBob USB to I2C Interface external device allows communications via a USB port of a laptop or PC that can be used with the provided MPS software GUI. As such this is the recommended communication interface for use with this interface card for initial bench evaluation. 6. S1/S21 enables/disables (turns “on”/“off”) the main output by connecting PS_ON_L to the respective 12VSTBY Return. Close S1/S21 to enable (turn “on”) the respective power module 12VDC Main Output. www.murata-ps.com/support 08 Feb 2016 ACAN64.A01 Page 5 of 6 D1U54P-12-CONC ACAN-64 Connector Card Application Note CONFIGURATION NOTES: 7. S7/S27 are a four (4) position DIL/DIP switches that is intended to select the User configurable bits that assign the variable address for I2C communications with the power module. The D1U54x products series’ employs an analogue input that is used to set the address of the internal slave devices (EEPROM and microprocessor) used for digital communications. Connection of a suitable resistor to +VSB_Return, in conjunction with a resistor divider chain (internal to the power module), will configure the required address. However since the purpose of this connector card is to provide a convenient means to evaluate the D1U54x products, this method has been replaced by an analogue multiplexer device that allows selection of the slave address via a “pin strap” method using three address bits (configured via S7/S27). S7/S27 S7/S27 S7/S27 Position #3 (A2) Position #2 (A1) Position #1 (A0) (Serial Address BIT 2) (Serial Address BIT 1) (Serial Address BIT 0) LOW LOW LOW LOW HIGH HIGH HIGH HIGH LOW LOW HIGH HIGH LOW LOW HIGH HIGH LOW HIGH LOW HIGH LOW HIGH LOW HIGH Power Module Main Controller (Serial Comm Slave Address) 0xB0 0xB2 0xB4 0xB6 0xB8 0xBA 0xBC 0xBE Power Module Main EEPROM (Serial Comm Slave Address) 0xA0 0xA2 0xA4 0xA6 0xA8 0xAA 0xAC 0xAE The address convention uses 7-bit left shifted Slave Device addressing with the Read/Write bit either a “0” (Write) or a “1” (Read). The addresses above assume the Read/Write bit is a “0”. S7/S27 is shown in the diagram opposite (also refer to the schematic). With any of the DIL switches (1, 2, & 3) set to the “off” (open) position, the corresponding address line (A0/A1/A2 respectively ) shall be set to a logic level high (by action of the 3K32K ohm pull up resistor upon the Interface Connector Card. Operating the appropriate switch to the “on” (closed) position will connect the appropriate line to a logic level low. Note: The switch position DIL Position #4 is unused and has no connection (NC) on the interface connector card. NB: The D1U54x Series employs “left shifted” 7-Bit addressing; where Bit “0”of the device address is the Read/Write bit. The addresses, as shown above, assume that the Read/Write bit is a logic level “0”. www.murata-ps.com/support 08 Feb 2016 ACAN64.A01 Page 6 of 6
