ATI isolated DC-DC power modules deliver regulated medium- to high-voltage DC outputs from a standard 12V or 24V supply, with complete galvanic isolation between input and output. All ATMV-series modules share a common set of key specifications: 1500VDC isolation voltage, ±1% output ripple @ 20MHz, automatic-recovery short-circuit protection, full aluminum shielded DIP package, and -40°C to +85°C operating range. Both single-rail and bipolar (±) output variants are available across the full product range.
Isolated vs. non-isolated DC-DC converters
An isolated DC-DC converter maintains complete galvanic separation between input and output — their grounds are fully independent. This eliminates ground loops, rejects common-mode noise, and protects sensitive circuits from high-voltage transients. A non-isolated converter shares a common ground and is more compact and cost-effective where isolation is not required.
Key parameters to consider when selecting a module
Nominal output voltage; maximum output current; input voltage range (all ATMV modules have a 2:1 input range); single or bipolar output; power rating; isolation voltage; efficiency; output ripple; and operating temperature. Full model selection tables with pricing and datasheets are available on each series page.

Frequently asked questions
What is an isolated DC-DC power module?
An isolated DC-DC power module converts one DC voltage to another while maintaining complete galvanic isolation between input and output — the grounds are fully independent. This eliminates ground loops, suppresses common-mode noise, and protects sensitive circuits from high-voltage transients, making it the fundamental architecture for PMT bias supplies, ion pump sustain circuits, piezo drivers, and any system where the output ground must float independently of the input.
What is the difference between isolated and non-isolated DC-DC converters?
Isolated converters provide full electrical separation (independent grounds) for superior noise rejection and safety in high-voltage or precision signal environments. Non-isolated converters share a common ground and are more compact and lower-cost for low-voltage point-of-load use where isolation is not a requirement.
What output voltages are available for 12V input modules?
The ATMV12V series covers single outputs from 50V to 600V and bipolar outputs from ±40V to ±300V, across power ratings of 4W, 6W, 8W, 12W, 15W, and 20W. Full model tables with pricing and datasheets are on the 12V series page.
What output voltages are available for 24V input modules?
The ATMV24V series offers single outputs from 100V to 500V and bipolar outputs from ±100V to ±250V at 20W, with efficiency up to 85%. Full details are on the 24V series page.
What isolation voltage do ATI modules provide?
All ATMV-series modules provide 1500VDC input-to-output isolation within a full aluminum shielded DIP housing that also provides complete EMI shielding.
Can ATI supply custom configurations?
Yes. ATI has 27+ years of precision power design experience and supports custom configurations across all output voltages, power levels, packaging formats, and certifications. Contact ATI with your specifications.
