Performance Specications and Ordering Guide
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 specied with
an external 0.47F multi-layer ceramic capacitors installed across their output pins.
Load regulation is specied over no load-100% load conditions. 1.2-5V models are
stable and regulate under no-load conditions. 12/15V models have minimum loading
requirements. See Performance/Functional Specications.
Nominal line voltage, no-load/full-load conditions.

I/O Connections
UWR 26-40W DC/DC's are designed so an On/Off Control function
with either positive polarity (no sufx), or negative polarity ("N" sufx)
can be added to the pin 4 position.
