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. Screening 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) RHA level of MIL-PRF-38534, which is defined as “no RHA”. See Table 10 on page 15 for more information. 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. Crane Aerospace & Electronics Power Solutions – Interpoint Products 10301 Willows Rd. NE, Redmond, WA 98052 +1.425.882.3100 • [email protected] www.craneae.com/interpoint On dual output models negative output regulation is maintained by tightly coupled magnetics. 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. Wide Voltage Range The SMSA converters are designed to provide full power operation over the full 16 to 40 volt range. An undervoltage lockout feature keeps the converter shutdown below approximately 13 volts to ensure smooth initialization. Dynamic Response The SMSA feed-forward compensation system p rovides excellent dynamic response and noise rejection. Audio rejection is typically 50 dB (“Figure 15” 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. 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 volts. In the inhibit mode, a maximum of 4 mA must be sunk from the inhibit pin at 28 volt input.

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 +125°C minimum. Burn-in is a powered test. table 2: environmental Screening anD rha–Dc-Dc converterS prototype, claSS h anD claSS k, rha p or r Table 10: Environmental Screening and RHA Levels SMSA Single and Dual, SMSA Rev AD - 2014.08.26.
