Converters offers up to 20. watts of power in a.smail aluminum case. Units are avail--.- able in single, dual or triple outputs. All units include input and output filtering to meet stringent EMI requirements. The convert- er can offer regulation of better than 1% at end of life, typical 12 year mission. The units can operate from bus voltages of 20 VDC to 46 VDC over a 35 percent range. The input to output isolation is 1 megohm minimum. All DC/DC. Converters can be.commanded ON/OFF with a com- mand line. Telemetering is provided to give the ON/OFF status of the DC/DC Converter. The Model: FE-280A series uses a constant frequency pulse width. modulated, current mode control switching regulator design with a switching frequency of 250 kHz nominal. Transformer coupling is implemented in the forward power circuit and feedback loop for high isolation and reliability. All active circuitry is contained:in the hybrid. The magnetics and the input-output filters are mounted on a multilayer printed. circuit. board with the hybrid. All power components are directly coupled to the baseplate for low thermal resistance. (Maximum junction ternperature at ambient 60C is 95C). Figure A shows the packaging concept. The above features are incorporated in our standard designs. Modificatons of these units.can give unlimited flexibility. Some options that can be incorporated into these designs are: 1. Synchronized switching rate; used to control interference in critical applications. 2. Bus inputs available (20V - 60V). 3. Reverse Polarity protection. 4. Commands for ON and OFF: 5. Input preregulator for improved ripple rejection. FEI s exceptional reliability is due to tight control of quality. This is facilitated by a high degree of vertical integration, which allows, us to take full responsibility at every step. The thin and thick film hybrids we design and produce (in. Class 10,000 cleanrooms) meet levels S and B of MIL-M-38510 and have been certified by prime contractors. Our certified instructors in turn train and certify. our operators to MIL-STD-2000. Our soldering meets WS-6536 (USN), MIL- S-45743E (USAF) and: NHB 5300.4. (341) (NASA). The FEI management system. focuses on quality and exceeds the requirements of MIL-Q-9858A, monitored by DCAS. PC board design and fabrication is QPL-listed for MIL-P- 55110D = types GF, GY, GR and Gl, and has been qualified in space. We are conducting a continuing. TOM initiative to. produce the highest quality product. Reliabiliiy by Desian This enviable record testifies to our dedication to reliable design and process control. Wherever possible, proven sub-assemblies are used in our custom designs. These iriclude our own hybrids, qualified for space. Semi-conductors and other parts are derat- ed by at least. 2:1. electrically and: mechanically, and cOnsena: oo Svely rated for thermal and tadiation stress.
