NEW Interpoint DC to DC Power Supply # MTR2812SF - 28 VOLT INPUT – 30 WATT. Parts are surplus from a project and have never been used. Packages are sealed but opened for photo. Offered at a significant discount. FEATURES • –55° to +125°C operation • 16 to 40 VDC input • Fully isolated • Magnetic feedback • Fixed frequency 600 kHz typical • Topology – Single Ended Forward • 50 V for up to 50 ms transient protection • Inhibit and synchronization functions • Indefinite short circuit protection • Up to 30 watts output power • Trim and remote sense on single output models • Up to 84% efficiency 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. 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. 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.
