SMTR SERIES 30 WATT
DESCRIPTION
The SMTR SeriesTM of 28 volt DC/DC converters offers up to 30 watts of output power from single or dual output configurations. The operate over the full military temperature range of -55C to +125C with up to 84% efficiency. SMTR converters are packaged in hermetically sealed metal enclosures, 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 should be connected to input common pin when not in use.
SCREENING AND REPORTS
SMTR converters offer three screening options (Standard, Class H, or Class K) and two levels of radiation hardness (O or R). See Tables 1, 2, and 3 for more information. Detailed reports on product performance are also available and are listed in Table 4.
WIDE VOLTAGE RANGE
SMTR converters are designed to provide full power operation over a full 16 to 40 Vdc voltage range. Operation below 16 volts, including MIL-STD-704D emergency power conditions is possible with derated power.
CONVERTER DESIGN
The SMTR 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 by using a 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. 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. SMTR 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. For the lowest noise performance, connection of the case to input common is recommended. The connection can be hard-wired or AC coupled with a small ceramic bypass capacitor.
IMPROVED DYNAMIC RESPONSE
The SMTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB. The min. to max. step line transient response is typically less than 4%.
INHIBIT FUNCTION
SMTR 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 (0.8V) 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 Vdc. In the inhibit mode, a maximum of 8 mA must be sunk from the inhibit pin.

FIGURE 2: REMOTE SENSE2, 3
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 to maintain specified performance. 2. If neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts. 3. CAUTION: The converter will be permanently damaged if the positive 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.
