DESCRIPTION  
step load transient is as low as 1.3% with a 150 msec recovery time.  
Input ripple current is typically 35 mA p-p with output ripple voltage  
typically 30 mV p-p .  
The SMHF Series™ of 28 V DC/DC converters offers a wide input  
voltage range of 16 to 40 volts and up to 15 watts of output power.  
The units are capable of withstanding short term transients up to 50  
volts. The package is a hermetically sealed, seam-welded metal  
case. Flanged and non-flanged models are available.  
INHIBIT FUNCTION  
SMHF converters provide an inhibit terminal that can be used to  
disable internal switching, resulting in no output and very low quies-  
cent input current. The converter is inhibited when a TTL compatible  
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 open-collector  
gate. The open circuit output voltage associated with the inhibit pin  
is 8.5 to 12 VDC. In the inhibit mode, a maximum of 12 mA must be  
sunk from the inhibit pin at 28 VDC input.  
SCREENING AND REPORTS  
SMHF converters offer three screening options (Standard, Class H,  
or Class K) and three levels of radiation hardness (O, L, and R). See  
Tables 1, 2, and 3 for more information. Detailed reports on product  
performance are also available and are listed in Table 4.  
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. 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.  
SYNCHRONIZATION  
A synchronization feature is included with the SMHF Series that  
allows the user to match the switching frequency of the converter to  
the frequency of the system clock. An external synchronization  
feature is included that allows the user to adjust the nominally  
550kHz operating frequency to any frequency within the range of  
500 kHz to 600 kHz. This is initiated by applying a TTL compatible  
input of the desired frequency to pin 5.  
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 output load  
current and providing a constant current output above the overload  
point.  
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.  
HIGHER POWER DENSITY  
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 foot-  
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.  
print of 1.7 in , this low profile package offers a total power density  
of up to 30 watts per cubic inch.  
LOW NOISE, HIGH AUDIO REJECTION  
The SMHF converters’ 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%
