The units are capable of withstanding short term transients up to 50 volts. The package is a hermetically sealed, projection-welded metal case. Flanged and non-flanged models are available. the output load current and providing a constant current output above the overload point. HigHer Power DenSity Screening SMHF converters offer screening options to Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O) or “R”, per MIL-PRF-38534. Interpoint model numbers use an “O” in the RHA designator 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. The SMHF converters are switching regulators that use a quasisquare wave, single-ended forward converter design with a constant switching frequency of 550 kHz. Isolation between input and output circuits is provided with a transformer in the forward path and a temperature compensated opto-coupler in the feedback control loop. The opto-coupler is radiation hardened and is especially selected for space applications. For the SMHF dual output models, cross regulation is maintained by tightly coupled output magnetics. Up to 70% of the total output power is available from either output, providing the opposite output is simultaneously carrying 30% of the total output power. Predictable current limit is accomplished by directly monitoring The SMHF Series offers a new standard of performance for small size and high power density. At just 0.33 inch high and a total footprint of 1.7 in2, this low profile package offers a total power density of up to 30 watts per cubic inch. The SMHF converter’s feed-forward compensation system provides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB. Typical output voltage response for a 50% to 100% step load transient is as low as 1.3% with a 150 µS recovery time. Input ripple current is typically 35 mA p-p with output ripple voltage typically 50 mV p-p . SMHF 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 logic low (≤0.8 – output disabled) 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 opencollector gate. The open circuit output voltage associated with the inhibit pin is 8.5 to 12 VDC. In the inhibit mode, a maximum of 4 mA must be sunk from the inhibit pin at 28 VDC input.

This allows the user to adjust the nominally 550 kHz operating frequency to any frequency within the range of 500 kHz to 600 kHz. This is initiated by applying a compatible input of the desired frequency to pin 5. The initial transition on the sync pin should be a negative transition (i.e. from high state to low state) unDervoLtAge Lockout Undervoltage lockout prevents the units from operating below approximately 14 VDC input voltage to keep system current levels smooth, especially during initialization or re-start operations. SHort circuit Protection SMHF Series converters provide short circuit protection by restricting the output current to approximately 115% of the full load output current. The output current is sensed in the secondary stage to provide highly predictable and accurate current limiting, and to eliminate foldback characteristics.

Our EMI filters are designed exclusively with passive components providing maximum tolerance for space environment requirements. 2. Interpoint model numbers use an “O” in the RHA designator position to indicate the “-” (dash) Radiation Hardness Assurance level of MIL-PRF-38534, which is defined as “no RHA”. 3. Space Prototype (O), non-QML, products do not meet all of the requirements of MIL-PRF-38534. 4. Redmond site, Interpoint, has a Radiation Hardness assurance plan on file with DSCC. Our SMD products with RHA “P”, “R," "F" and "H" code meet DSCC requirements. 5. Space converters are available with Radiation Hardness Assurance (RHA) levels of “O” and “R” with the following exceptions: SMRT28xxx is only available with Radiation Hardness Assurance (RHA) levels of “O” “P”, “R” and “F”. SMHP120xxx is only available with Radiation Hardness Assurance (RHA) level of “O”. Space filters are only available with Radiation Hardness Assurance (RHA) levels of “O” and “H”.
