Performance/Functional Specifications Typical @ TA = +25°C under nominal line voltage and full-load conditions unless noted. ➀ ➀ These power converters require a minimum 10% loading to maintain specified regulation. Operation under no-load conditions will not damage these devices; however they may not meet all listed specifications. ➀ The current limit inception point is dependent on the input voltage. Therefore, it is possible to draw current beyond the rated capacity. Users should fully characterize their load conditions.

Brief duration only. Fusing recommended. Output Overvoltage Protection None Output Current Maximum current and short-circuit duration are model dependent. “D12” and “D48” models can withstand sustained output short circuits. Storage Temperature –55 to +100°C Lead Temperature (soldering, 10 sec.) +280°C These are stress ratings. Exposure of devices to greater than any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/ Functional Specifications Table is not implied or recommended. Absolute Maximum Ratings Floating Outputs Since these are isolated DC/DC converters, their outputs are “floating.” Any BST model may be configured to produce an output of 10V, 24V or 30V (for ±5V, ±12V or ±15V models, respectively) by applying the load across the +Output (pin 6) and –Output (pin 8), with either output grounded. The Common (pins 5 and 7) should be left open (unconnected). Minimum 20% loading is recommended under these conditions. Filtering and Noise Reduction All BST 3 Watt DC/DC Converters achieve their rated ripple and noise specifica- tions without the use of external input/output capacitors. In critical applications, input/output ripple and noise may be further reduced by installing electrolytic capacitors across the input terminals and/or low-ESR tantalum or electrolytic capacitors across the output terminals. Output capacitors should be con- nected between their respective output pin (pins 6 and 8) and Common (pins 5 and 7) as shown in Figure 2. The caps should be located as close to the power converters as possible. Typical values are listed in the tables below. In many applications, using values greater than those listed will yield better results.
