CHOOSING THE RIGHT CONVERTER: A GUIDE for DC/DC Converters
Step 1: Do you need Isolation? (An isolated converter has outputs that are floating and not
connected to the inputs i.e. they are galvanically isolated)
No isolation needed: Check our Innoline parts first (R-78 series, R-5xxx, R-6xxx and
R-7xxx series)
Isolation needed: decide whether you need 1kVDC/1 sec (standard) or 1.6VDC/
1 sec, 2kVDC/1 sec, 3kVDC/1 sec, 4kVDC/1 sec, 5.2kVDC/1 sec or 6kVDC/1 sec.
Step 2: Decide on the output voltage and number of outputs: single, dual bipolar (+/-), dual
isolated or triple.
It is also important to decide whether the output voltage needs to be regulated or
unregulated.
Unregulated converters are offered standard without short circuit protection or
optionally with short circuit protection (option /P)
All Series are available with single outputs.
Please note that a dual output converter can be used as a single output by leaving
the common pin unconnected i.e. +/-5V = 10V, +/-12V = 24V, +/-15V = 30V, etc.
Step 3: Decide on the output current. The output voltage times the output current gives the
output power of the converter in Watts.
DC/DC converters are designed to run at full load, so only round up the power if a
suitable converter is not available.
e.g. 5V @ 150mA = 0.75W = 1W converter.
e.g. +/-15V @ +/-1A = 30W = 30W converter.
Step 4: Decide on the input voltage. Standard input voltage ranges are:
3.3, 5, 9, 12, 15, and 24VDC with +/-10% tolerance
4.5 ~ 9V, 9 ~ 18V, 18 ~ 36V and 36 ~ 72VDC with 2:1 input voltage range
9 ~ 36V and 18 ~ 72VDC with 4:1 input voltage range.
Step 5: Decide on the case style and pin-out. Many Recom series are available in either
through hole or surface mount styles and with several pin-out options, including
Remote On/Off Control.
Step 6: Use either the Selection guide or Contents guide at the start of each section to
find the most appropriate converter.
