Floating Outputs
Since these are isolated DC/DC converters, their outputs are “fl oating.” Any
BST model may be confi gured 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 specifi 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
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.
