DESCRIPTION The MTR Series™ of DC/DC converters offers up to 30 watts of output power from single, dual, or triple output configurations. 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. 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 quasi-TTL signal at any duty cycle between 40% and 60%. The sync pin must be connected to input common pin when not in use. 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 and shunt regulators. 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 500 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. MTR converters are provided with internal filtering capacitors that help reduce the need for external components in normal operation. For systems that require compliance with MIL-STD-461C’s CE03 standard, Interpoint offers filter/transient suppression modules (including the FMC-461, FMD-461 and FM-704A series filters) which will result in compliance. Contact your Interpoint representative for further details. WIDE VOLTAGE RANGE MTR converters are designed to provide full power operation over a full 16 to 40 VDC voltage range. Operation below 16 volts, including MIL-STD-704E emergency power conditions is possible with derated power. Refer to the low line dropout graph (Figure 22) for details. IMPROVED DYNAMIC RESPONSE The MTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB. The minimum to maximum step line transient response is typically less than 4%. 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 a TTL compatible low (≤0.8 V) is applied to the inhibit pin. The unit is enabled when the pin, which is internally connected to a pull-up resistor, is left unconnected or is connected to an open-collector gate. The open circuit output 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. 89 MTR SERIES 30 WATT ABSOLUTE MAXIMUM RATINGS Input Voltage • 16 to 40 VDC Output Power • 25 to 30 watts depending on model Lead Soldering Temperature (10 sec per pin) • 300°C Storage Temperature Range (Case) • –65°C to +135°C DC/DC CONVERTERS SYNC AND INHIBIT Sync (500 to 675 kHz) • Duty cycle 40% min, 60% max • Logic low 0.8 V max • Logic high 4.5 V min, 5 V max • Referenced to input common • If not used, connect to input common Inhibit TTL Open Collector • Logic low (output disabled) Voltage ≤0.8 V Inhibit pin current 8.0 mA max • Referenced to input common • Logic high (output enabled) Open collector TYPICAL CHARACTERISTICS Output Voltage Temperature Coefficient • 100 ppm/°C typical single and dual outputs • 200 ppm/°C main, 300 ppm/°C aux triple output Input to Output Capacitance • 50 pF typ (100 pF typ triple outputs) Current Limit • 115% of full load typical Isolation • 100 megohm minimum at 500 V Audio Rejection • 40 dB typ (50 dB typ triple output)l Conversion Frequency • Free run 550 min, 600 typ, 650 max kHz • External sync 500 to 675 kHz Inhibit Pin Voltage (unit enabled) • 9 to 11 V RECOMMENDED OPERATING CONDITIONS Input Voltage Range • 16 to 40 VDC continuous • 50 V for 50 msec transient Case Operating Temperature (Tc) • –55°C to +125°C full power • –55°C to +135°C absolute Derating Output Power/Current • Linearly from 100% at 125°C to 0% at 135°C Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
