DESCRIPTION

The Interpoint® SMTR Series™ of 28 volt dc-dc converters offers up to 30 watts of output power from single or dual configurations. They operate over the full military temperature range of -55°C to +125°C 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. Screening SMTR converters offer screening options to space prototype (O), Class H or K and radiation hardness assurance (RHA) levels P - 30 krad(Si), L - 50 krad(Si) or R - 100 krad(Si). Single event effects (SEE) LET performance to 86 MeV cm 2/mg. See Table 9 on page 13 and Table 10 on page 14 for more information. converter DeSign 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. SMTR converters have an internal input filter that helps reduce the need for external components in normal operation. Use our SFMC EMI input filter to meet the requirements of MIL-STD- 461C’s CE03. 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 approximately 140% of the maximum rated output current. 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 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. WiDe voltage range SMTR converters are designed to provide full power operation over the input voltage range of 16 to 40 volts. Operation below 16 volts, including MIL-STD-704D emergency power conditions is possible with derated power. Refer to the low line dropout graph, Figure 22 on page 10, for details.

The SMTR Series feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 40 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 voltage and very low quiescent input current. The converter is inhibited when the inhibit pin is pulled below 0.8 V and enabled when its inhibit pin is left floating. An external inhibit interface should be capable of pulling the converter’s inhibit pin below 0.8 V while sinking the maximum inhibit current and also allowing the inhibit pin to float high to enable the converter. A voltage should not be applied to the inhibit pin. The open circuit voltage present on the inhibit pin is 9 to 11 V.

Do not exceed maximum power. 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. 4. When using remote sense for voltage compensation or when using remote sense for trim, the output will drift over temperature.

Notes 1. Our Redmond facility has a DLA approved RHA plan for Interpoint power products. Our SMD products with RHA “P”, “L” or “R” code meet DLA requirements. 2. Non-QML prototype products may not meet all of the requirements of MIL-PRF-38534. 3. All processes are QML qualified and performed by certified operators. 4. “O” in the RHA designator position in Interpoint model numbers indicates DLA RHA “-” defined as no RHA. 5. Not required by DLA but performed to assure product quality. 6. Burn-in temperature designed to bring the case temperature to +125°C minimum. Burn-in is a powered test. 7. High dose rate test. 8. Low dose rate test. 9. No destructive events or SEL. Crane Aerospace & Electronics Power Solutions SMTR Series Single and Dual, SMTR Rev AC - 2015.10.14.
