Output Configuration:
Part Number Suffixes
UWR 26-40W DC/DC's are designed so the On/Off Control function on pin 4 can be ordered with
either positive (open or "high" = on) or negative (open = off, pull low = on) polarity. The standard
part number with no suffix denotes positive polarity. Add an "N" suffix to select negative polarity.
No Suffix
"N" Suffix On/Off Control function (negative polarity) on pin 4. Standard for D48.
Typical at TA = +25°C under nominal line voltage and full-load conditions, unless noted.
Ripple/Noise (R/N) is tested/speciifed over a 20MHz bandwidth. All models are specified with an external 0.47μF
multi-layer ceramic capacitor installed across their output pins. Using a 10μF multi-layer ceramic capacitor instead
(e.g. TDK part no. C3225X5R1C106M) will further reduce the R/N to 35mVp-p typical and 75mVp-p maximum.
Load regulation is specified over 0-100% load conditions. All models are stable and regulate within spec under
no-load conditions, with perhaps a slight increase in output ripple/noise.
Nominal line voltage, no-load/full-load conditions.
Please refer to the part number structure when ordering.
