Crane Aerospace & Electronics Power Solutions SLH Single and Dual DC/DC Converters 28 Volt input – 1.5 Watt – Pending Revision C Release Features Small size, 0.8 inches2 (5.16 cm2) • Operating temperature -55° to +125°C • Qualified to MIL-PRF-38534 Class H and K • Radiation hardness assurance (RHA) to level R 100 kRad(Si) • Input voltage range 16 to 40 VDC • Fully isolated, magnetic feedback • Inhibit function • Indefinite short circuit protection models VDC Output • High power density, 88% efficiency singles 5 12 15 description With a miniature footprint of just 0.8 square inches, the SLH Series™ of 28 V DC/DC converters delivers 1.5 watts of output power while saving significant board area. The wide input voltage range of 16 to 40 VDC accepts the varying voltages of space, military, or aerospace bus power and tightly regulates output voltages to protect downstream components. Single output models feature outputs of 5, 12, or 15 volts, and dual output models feature outputs of ±5, ±12 and ±15 volts. Screening SLH converters offer the following screening options: Space Prototype (O), Class H, or Class K. Radiation tolerant to Radiation Hardness Assurance (RHA) levels of “-” (O) 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 “Class H and K, QML Screening” tables for more information. When used with Interpoint’s STF28-461 filter, the combination will meet the requirements of MIL-STD-461C, CE03. Inhibit Function The SLH Series incorporates an inhibit terminal that can be used to disable internal switching. The converter is inhibited when an active low (≤ 0.5 V) signal is applied to the inhibit pin (pin 7). In the inhibit mode the inhibit pin sources up to 2 mA maximum. The converter resumes normal operation when an open circuit is applied to the inhibit pin. The open circuit voltage of the inhibit is 7 to 8 volts. Do not apply an external pull-up to the converter. Protection Features All models include a soft-start function to prevent large current draw and minimize overshoot. The converters provide short circuit protection (by restricting the current) and output overload protection. Convenient Packaging Converter Design SLH Series DC/DC converters incorporate a flyback topology with a variable switching frequency. Feedback provides output voltage regulation. Output voltage is magnetically fed back to the input side of the PWM to regulate output voltage. The SLH Series converters are packaged in hermetically sealed metal cases which provide EMI/RFI shielding. Up to 80% of the load of the dual output models may be on one output providing that the other output carries a minimum of 20% of the total load. The dual models can be used as a single output voltage by connecting the load between positive and negative outputs, leaving the common unconnected resulting in double the output voltage. (for example, SLH2805D can be used as a 10 VDC output.)
