Power announces new additions to its I series of low power isolated DC/DC
converters. The series, now comprising of 11 families, offer a range of
industry standard mounting options including SIP, DIP and DIP24 with single and
dual outputs, and now with either regulated or unregulated outputs. Four output
power versions are available, 1 W, 1.5 W, 2 W and 3 W. The converters size, as
small as 0.46 x 0.24 x 0.38 inches (11.68 x 6.1 x 9.65 mm) for the 1 W models,
occupies very little PCB space and allows designers to reduce the size of their
end products. The standard pin out configurations make the units an ideal low
cost drop-in replacement part, without any need for PCB redesign. All models
provide either 1,000 VDC or 3,000 VDC input to output isolation for a period of
up to 1 minute, depending on the family. The IH and IN series also has 4,000,
5,200 and 6,000 VDC isolation options available. Input voltages covering the
nominal values of 3.3, 5, 12, 24 or 48 VDC +/- 10% are available, with the IW
and IU series offering a wide 2:1 input range, accepting 4.5–9, 9–18, 18–36 or
36–72 VDC. Single and dual output models
are offered. The single output voltages are 3.3, 5, 9, 12, 15 or 24 VDC. Dual
outputs provide +/-3.3, +/-5, +/-9, +/-12, +/-15 or +/- 24 VDC. All units, with the
exception of the IS, operate on full power from -40 degrees C to + 85 degrees C
without derating. The IS model is rated from -25 degrees C to + 85 degrees C,
with derating above +70 degrees C. All models are able to operate in most
environments without the need for additional heat sinking or forced airflow. With an MTBF in excess of 1
million hours, the I series is an extremely reliable product that will help
ensure extended lifetime in the customer's end products. Prices start from $4.55 for
the 1W IE models in OEM quantities.
