Crane Aerospace & Electronics Power Solutions SMFL Single and Dual DC/DC Converters 28 Volt input – 65 Watt Features Fully qualified to Class H or K –55° to +125°C operation 16 to 40 VDC input Fully Isolated Magnetic feedback Fixed frequency, 600 kHz typical Topology – Single Ended Forward Inhibit input side and output side Sync function 50 V for up to 120 ms transient protection VDC Output single 3.3 5 12 15 dual ±5 ±12 ±15 models Output trim on single output models Indefinite short circuit protection Up to 85% efficiency / 43 W/in3 Parallelable up to 148 watts Remote sense on single output models 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 www.DataSheet4U.com inches, giving the series an overall power density of up to 45 watts per cubic inch. description Inhibit Screening SMFL converters offer the following screening options: Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O) or “R”, per MIL-STD-38534. Interpoint model numbers use an “O” in the RHA designator position to indicate the “-...
