description
®
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 1.8% with a 150
µs recovery time, typical. See Table 5 on page 5 for more
information.
The Interpoint SMHF Series™ of 28 volt dc-dc converters offers
a wide input voltage range of 16 to 45 volts and up to 15 watts of
output power. The units are capable of withstanding transients up
to 50 volts for up to 50 ms.
Screening
SMHF converters offer screening to 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
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. 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. See Table 5 on page
5 for more information.

to 86 MeV cm /mg. See Table 10 on page 15 for more
information.
converter DeSign
The SMHF converters are switching regulators that use a
quasi-square wave, single-ended forward converter design with
a constant switching frequency of 550 kHz typical. 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.
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.
Dual output models maintain cross regulation with 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.
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 volts input to keep system current levels
smooth, especially during initialization or re-start operations.

1. See Figure 4 above for an example of a model number.
2. Output Voltage: An R indicates a decimal point. 3R3 is 3.3 volts out. The values of 3.3 and 5.2 are only available in single output models.
3. Number of Outputs: S is a single output and D is a dual output
4. Case Options: For the standard case (Figure 27 on page 12) leave the Case Option blank. For the flanged case option (Figure 28 on page 13), insert the letter F
in the Case Option position.
5. Screening: A screening level of O is a space prototype and is only available with RHA O. See Table 9 on page 14 and Table 10 on page 15 for more information.
6. RHA: 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.” RHA O is only available with screening level O. See Table 10 on page 15 for more information.

1. ꢀuaranteed by characterization test and/or analysis. Not a production test.
5. Indefinite short circuit protection not guaranteed above 125°C (case)
6. Recovery time is measured from application of the transient to point at which
is within regulation.
7. Response of either output with the opposite output held at half of the total output
power.
2. 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. Each
output must carry a minimum of 30% of the total output power in order to maintain
regulation on the negative output.
