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 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 tolerant and is especially selected for space applications. On 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 output load current and providing a constant current output above the overload point. The small size, high power density SMHF Series low profile package provides 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 s recovery time, typical. Input ripple current is typically 45 mA p-p with output ripple voltage typically 15 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 the inhibit pin is pulled low (0.8 V- output disabled). 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 7.5 to 12 VDC. In the inhibit mode, a maximum of 5 mA must be sunk from the inhibit pin at 28 VDC input. The SMHF Series' synchronization feature allows the user to match the switching frequency of the converter to the frequency of the system clock. This allows the user to adjust the nominal 550 kHz operating frequency to any frequency within the range of 500 kHz to 600 kHz 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). SMHF Series converters provide short circuit protection by restricting the output current to approximately 140% 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. 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.

Notes: 1. Our Redmond facility has a DLA approved RHA plan for Interpoint power products. Our SMD products with RHA "P" or "R" code meet DLA requirements. 2. "OO" prototypes are non-QML products and may not meet all of the requirements of MIL-PRF-38534. "O" in the RHA designator position in Interpoint model numbers indicates DLA RHA "-" defined as no RHA. 3. All processes are QML qualified and performed by certified operators. 4. Not required by DLA but performed to assure product quality. 5. Burn-in temperature designed to bring the case temperature to +125C minimum. Burn-in is a powered test.
