On dual output models, up to 70% of the rated output power can be drawn from either the positive or negative outputs. Current sharing allows the units to be paralleled for total power of up to 285 watts. The welded, hermetically sealed package is only 3.005 x 1.505 x 0.400 inches. Screening SMFLHP converters offer screening options to Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of "-" (O), "P" or "R", per MIL-PRF-38534. Interpoint model numbers use an "O" in the RHA designator position to indicate the "-" (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as "no RHA". See "Table 9: Element Evaluation" on page 14 and "Table 10: Environmental Screening and RHA Levels" on page 15 for more information. Crane Aerospace & Electronics Power Solutions - Interpoint Products 10301 Willows Rd. NE, Redmond, WA 98052 +1 425.882.3100 * power@crane-eg.com www.craneae.com/interpoint Design Features The SMFLHP Series converters are switching regulators that use a quasi-square wave, single ended forward converter design with a constant switching frequency of 600 kHz. Isolation between input and output circuits is provided with a transformer in the forward path and wide bandwidth magnetic coupling in the feedback control loop. The SMFLHP Series uses a unique dual loop feedback technique that controls output current with an inner feedback loop and output voltage with a cascaded voltage mode feedback loop. The additional secondary current mode feedback loop improves transient response in a manner similar to primary current mode control and allows for ease of paralleling. Tight load regulation is achieved through a wide-bandwidth magnetic feedback circuit. The output voltage on single SMFLHP models can be easily trimmed up by adding an external resistor. See "Figure 2: Sense Connections and Trim Table - Single Output Models" on page 3 for voltage changes with different resistor values. Page 1 of 15 Rev AA - 2013.08.31 The information in this document is a derivative of documents cleared by the Department of Defense (DoD) Office of Security Review (OSR) for public release.

Crane Aerospace & Electronics Power Solutions SMFLHP Single and Dual DC-DC Converters 28 Volt input - 100 Watt Inhibit converter is designated as a master. The SLAVE pin (pin 11) of the master is left unconnected and the MSTR/INH2 pin (pin 12) of the master is connected to the SLAVE pin (pin 11) of the slave units. The units designated as slaves have the MSTR/INH2 pin (pin 12) connected to the SNS RTN pin (pin 9) of the master unit. Figure 1 shows the typical setup for two or three units in parallel. The SMFLHP Series converters have two inhibit terminals (INH1 and INH2) that can be used to disable power conversion, resulting in a very low quiescent input current. An active low (<0.8 volts) is required between INH1 (pin 4) and Input Common (pin 2) to inhibit the converter. An active low (<0.5 volts) is required between INH2 (pin 12) and Output Common (pin 8) to inhibit the converter. The application of intermediate voltages to these pins (1.5 to 10.5 volts) should be avoided. Note that synchronizing the units together (though shown in the figure) is not required for current sharing operation. A second slave unit may be placed in parallel with a master and slave; this requires the TRI pin (pin 3) of the master unit to be connected to the SNS RTN pin (pin 9). Current Sharing and Parallel Operation Multiple SMFLHP converters may be used in parallel to drive a common load. See "Figure 1: Parallel Connections - Single Output Models" on page 2. Only single output models with SENSE and SNS RTN can be used in the share mode. In this mode of operation the load current is shared by two or three SMFLHP converters. In current sharing mode, one SMFLHP 28V Inhibit Sync In + - 1 2 3 4 5 6 When paralleled, up to 95% of the total combined power ratings of the SMFLHP converters is available at the load.
