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%
