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. 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. 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. 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. On dual output models negative output regulation is maintained by tightly coupled magnetics. Crane Aerospace & Electronics Power Solutions - Interpoint Products 10301 Willows Rd. NE, Redmond, WA 98052 +1.425.882.3100 * power@crane-eg.com www.craneae.com/interpoint 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. 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. 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.
