They operate over the full military temperature range with up to 84% efficiency. MTR converters are packaged in hermetically sealed metal cases, making them ideal for use in military, aerospace and other high reliability applications. The converters are offered with standard screening, "ES" screening, or fully compliant to "883" MIL-PRF-38534 Class H screening. Standard microcircuit drawings (SMD) are available. Converter Design The MTR converters are constant frequency, pulse-width modulated switching regulators which use a quasi-square wave, single ended, forward converter design. Tight load regulation is maintained via wide bandwidth magnetic feedback and, on single output models, through use of remote sense. On dual output models, the positive output is independently regulated and the negative output is cross regulated through the use of tightly coupled magnetics. The MTR Series triple output DC/DC converter's design includes individual regulators on the auxiliary outputs which provide for no cross regulation error when a minimum 300 mA load is maintained on the main (+5) output. Indefinite short circuit protection and overload protection are provided by a constant current-limit feature. This protective system senses current in the converter's secondary stage and limits it to approximately 115% of the maximum rated output current. Crane Aerospace & Electronics Crane Electronics, Inc.

Use our FMCE-0328, FMCE-0528 or FMCE-0828 EMI filter to meet the requirements of MIL-STD-461C CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and CS101 levels of conducted emissions. Or use the FM-704A for transient suppression and to meet MIL-STD-461C CE03. Synchronization Synchronizing the converter with the system clock allows the designer to confine switching noise to clock transitions, minimizing interference and reducing the need for filtering. In sync mode, the converter will run at any frequency between 500 kHz and 675 kHz. The sync control operates with a duty cycle between 40% and 60%. The sync pin must be connected to input common pin when not in use. Wide Input Voltage Range MTR converters are designed to provide full power over a full 16 to 40 VDC voltage range. Operation below 16 volts, including MIL-STD-704A emergency power conditions is possible with derated power. Refer to the low line dropout graph (Figures 22, 30 and 31) for details. Improved Dynamic Response The MTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 40 dB for singles and duals and 50 dB for triples. The minimum to maximum step line transition response is typically less than 4%. Page 1 of 22 MTR Rev H - 2011.03.17 Crane Aerospace & Electronics Power Solutions MTR Single, Dual and Triple DC/DC Converters 28 Volt input - 30 Watt Inhibit Function MTR converters provide an inhibit terminal that can be used to disable internal switching, resulting in no output and very low quiescent input current. The converter is inhibited when the inhibit pin is pulled below (<0.8 V). The unit is enabled when the inhibit pin, which is internally connected to a pull-up resistor, is left unconnected or is connected to an open-collector gate. The open circuit voltage associated with the inhibit pin is 9 to 11 V. In the inhibit mode, a maximum of 8 mA must be sunk from the inhibit pin.

Figure 2: Remote Sense Connection Notes for Remote Sense and Trim 1. When trimming output voltage and/or remote sensing, the total output voltage increase must be less than 0.6 volts at the converters pins. Do not exceed the maximum power. 2. If neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6. 3. CAUTION: The converter will be permanently damaged if the remote sense (pin 6) is shorted to ground. Damage may also result if the output common or positive output is disconnected from the load with the remote sense leads connected to the load. 4. When using remote sense for voltage compensation or when using remote sense for trim, the output will drift over temperature.
