Return Current Paths
These are non-isolated DC/DC converters. The Input Return, Output Return
and Logic Ground pins are all connected together internally. To the extent
possible, all input and load currents should be returned through the Input
Return and Output Return, respectively (via low-impedance runs). Any con-
trol signals applied to the On/Off Control pin should be referenced to Logic
Ground. The internal trace leading to Logic Ground is not designed to carry
high current. Consequently, devices should never be installed in a manner
that results in high current flow through Logic Ground (i.e., the Input/Output
Return pins should never be left open or connected via high-impedance paths).
I/O Filtering and Noise Reduction
All UNR 18-33W Series converters are tested and specified with external
470μF input capacitors (20m ESR, 6Arms ripple-current rating) and
external 22μF output capacitors (200m ESR). External input capacitance is
required and must be rated to handle the input ripple current as follows:
In critical applications, input/output ripple/noise may be further reduced by
installing additional I/O caps.

All models are tested and specified with an external 470μF input capacitor with a 20m
ESR and a 6Arms ripple-current rating, as well as a 22μF output capacitor with a 200m ESR.
See I/O Filtering and Noise Reduction for more details. These devices have no minimum-load
requirements and will regulate under no-load conditions. Listed specifications apply for both
"T" and "SM" models as appropriate.
See Output Overcurrent Detection for details.
See On/Off Control for details.
See Output Voltage Trimming for details.
For all models, output noise can be further reduced with the installation of additional
external output capacitors. See I/O Filtering and Noise Reduction for details.
