DESCRIPTION

The SMTR Series™ of 28 volt DC/DC converters offers up to 30 watts of output power from single, dual or triple output config- urations. They operate over the full military temperature range of -55°C to +125°C with up to 84% efficiency (up to 73% efficiency triple models). SMTR converters are packaged in hermetically sealed metal enclosures, making them ideal for use in military, aerospace and other high reliability applications. Sc r e e n i n g SMTR converters offer screening options to Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O), “P,” or “R,” per MIL-STD- 38534. Interpoint model numbers use an “O” in the RHA desig - nator position to indicate the “-” (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as “no RHA”. See “Class H and K, MIL-PRF-38534 Screening” tables for more information. co n v e r t e r DeSi g n The SMTR converters are constant frequency, pulse-width mod ulated 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. The SMTR Triple Series 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. SMTR converters have internal input filter 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 SFMC-461 and SFCS28-461), 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. 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 approxi - mately 125% of the maximum rated output current. Sy n c h r o n i z a t i o n Synchronizing the converter with the system clock allows the designer to confine switching noise to clock transitions, mini- mizing 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 an active high at any duty cycle between 40% and 60%. The sync pin should be connected to input common pin when not in use.

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 posi- tive 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. Trim Formulas Vout = desired output voltage; Rt = trim resistor 3.3V: Rt = 1300 * Vout – 4304 1.2475 5V: Rt = 1300 * Vout – 6512 1.2475 12V: Rt = 1300 * Vout – 15631 1.2475 15V: Rt = 1300 * Vout – 19498 1.2475 WiDe vo l t a g e ra n g e 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. im p r o v eD Dy n a m i c reSp o nSe The SMTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB (for Triple output models). The min. to max. step line transient response is typically less than 4%. in h i b i t Fu n c t i o n 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 an active 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.

The sum of the two Aux outputs is not to exceed 10 watts. The maximum load per Aux output is 7.5 watts. 3. To maintain regulation when operating the ±Aux at full load, a minimum load of 300 mA is required on the main output. For Aux loads less than full load, a lower load (<300 mA) on the main output will maintain regulation. 4. Measured on each output one at a time with the other outputs at full load. 5. Indefinite short circuit protection not guaranteed above 125°C (case). 6. Response of each output as all outputs are simultaneously transitioned. Main: 50% - 100% - 50% of main full load Auxiliaries: 25% - 50% - 25% each, of total auxiliary full load 7. Recovery time is measured from application of the transient to point at which Vout is within 1% of regulation. 8.
