Crane Aerospace & Electronics Power Solutions SMFL Single and Dual DC/DC Converters 28 Volt input – 65 Watt Features Parallel operation with current share, up to 3 units (148 watts) • Operating temperature -55° to +125°C • Qualified to MIL-PRF-38534 Class H and K • Radiation hardness assurance (RHA) to level R 100 kRad(Si) • Input voltage range 16 to 40 VDC • Transient protection 50 V for 120 ms • Fully isolated, magnetic feedback models • Fixed high frequency switching VDC Output • Remote sense and output trim on single output models single 3.3 5 12 15 • Inhibit function • Synchronization input and output • Indefinite short circuit protection dual ±5 ±12 ±15 • High power density, 85% efficiency description The SMFL Series™ 28-volt DC/DC converters are rated up to 65 watts output power over a -55° to +125°C temperature range with a 28 VDC nominal input. 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 148 watts. The welded, hermetically sealed package is only 3.0 x 1.5 x 0.40 inches, giving the series an overall power density of up to 43 watts per cubic inch. Screening SMFL converters, also available on SMD drawings, offer the following screening options: 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 Screening Tables 1 - 3 for more information. Design Features similar to primary current mode control and allows for ease of paralleling, but without the cost and complexity. The constant frequency, pulse-width modulated converters use a quasi-square wave single-ended forward design. Tight load regulation is achieved through a wide-bandwidth magnetic feedback circuit. The output voltage on single SMFL models can be trimmed to a specific output voltage by adding an external resistor (see Figure 1 for resistor values). Inhibit The SMFL 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 and no generation of switching noise. An active low (<0.8 volts) is required to inhibit the converter between INH1 (pin 4) and Input Common (pin 2). An active low (<0.5 volts) is required to inhibit the converter between INH2 (pin 12) and Output Common (pin 8). The application of intermediate voltages to these pins (1.5 to 10.5 volts) should be avoided. SMFL Series converters are switching regulators that use a quasi-square wave, single ended forward converter design with a constant switching frequency of 600 kHz typical. Sync Isolation between input and output circuits is provided with a transformer in the forward path and a wide bandwidth magnetic coupling in the feedback control loop. The SMFL uses a unique dual loop feedback technique that controls output current with an inner feedback loop and an output voltage with a cascaded voltage mode feedback loop. The additional secondary current mode feedback loop improves transient response in a manner Current and Parallel Operation Crane Aerospace & Electronics Electronics Group (Interpoint Brand) PO Box 97005 • Redmond WA 98073-9705 425.882.3100 • [email protected] www.craneae.com/interpoint Converters may be synced to an external clock (525 to 675 kHz) or to one another by using the sync in or out pins. The nominal free-run switching frequency is 600 kHz (see Application Note titled “Inhibit and Synchronization”). Multiple single output SMFL converters may be used in parallel to drive a common load. In this mode of operation the load current is shared by two or three SMFL converters.

Crane Aerospace & Electronics Power Solutions SMFL Single and Dual DC/DC Converters 28 Volt input – 65 Watt sharing mode, one SMFL 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). Note that synchronizing the units together is not required for current sharing operation. Operating Conditions and characteristics Input Voltage Range •16 to 40 VDC continuous •50 V for 120 ms transient 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).
