Floating Outputs
Since these are isolated DC/DC converters, their outputs are “?oating.” Any
BST model may be con?gured to produce an output of 10V, 24V or 30V (for
Environmental
±5V, ±12V or ±15V models, respectively) by applying the load across the

Filtering and Noise Reduction
All BST 3 Watt DC/DC Converters achieve their rated ripple and noise speci?ca-
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
? These power converters require a minimum 10% loading to maintain speci?ed regulation.
Operation under no-load conditions will not damage these devices; however they may not
meet all listed speci?cations.
? 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.
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.
