description

Predictable current limit is accomplished by direct monitoring

of the output load current, which results in a constant current

output above the overload point. Internal input and output filters

eliminate the need for external capacitors.

The SMSA Series™ of high frequency, space qualified, dc-dc

converters provide up to 5 watts output power over the full

military temperature range of -55°C to +125°C with up to 74%

efficiency. Thick-film hybrid techniques provide military/aerospace

reliability levels and optimum miniaturization. The hermetically

sealed case is 1.075 by 1.075 inches with a height of 0.270

inches. Power density for the SMSA Series converters is 16 watts

per cubic inch. The SMSA Series’ small size, light weight and

hermetically sealed metal packages make them ideal for use in

space, military, aerospace and other high reliability applications.

WiDe voltage range

The SMSA converters are designed to provide full power

operation over the full 16 to 40 VDC voltage range. An

undervoltage lockout feature keeps the converter shutdown

below approximately 13 VDC to ensure smooth initialization.

Screening

Dynamic reSponSe

SMSA converters offer the following screening options: Space

Prototype (O), Class H, or Class K. Radiation tolerant to

Radiation Hardness Assurance (RHA) levels of “-” (O), “P” or

“R”, per MIL-STD-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 “Table 10: Environmental Screening and RHA

Levels” on page 15 for more information.

The SMSA feed-forward compensation system provides excellent

dynamic response and noise rejection. Audio rejection is typically

50 dB (“Figure 15” on page 11). The minimum to maximum

step line transient response is typically less than 1% (“Figure 10”

on page 10 and “Figure 19” on page 11).

inhibit Function

SMSA converters provide an inhibit feature that can be used to

disable internal switching and inhibit the unit’s output. Inhibiting in

this manner results in low standby current, and no generation of

switching noise.

converter DeSign

The SMSA converters are switching regulators that use a flyback

converter design with a constant switching frequency of 500 kHz.

They are regulated, isolated units using a pulse width modulated

topology. Isolation between input and output circuits is provided

with a transformer in the forward power loop and an optical link in

the feedback control loop. Excellent input line transient response

and audio rejection is achieved by an advanced feed-forward

compensation technique.

The converter is inhibited when an active low (≤0.8 V) 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 9 to 11 VDC. In the

inhibit mode, a maximum of 4 mA must be sunk from the inhibit

pin at 28 VDC input.

On dual output models negative output regulation is maintained

by tightly coupled magnetics.
