About DC-DC Converters
DC-DC converters are fundamental building blocks in modern electronics, transforming input voltages to regulated output levels while providing electrical isolation. This isolation prevents ground loop interference and protects sensitive circuits from voltage spikes, making them indispensable in multi-voltage systems.
In applications ranging from factory automation to telecom base stations, these modules ensure stable power delivery despite fluctuating input sources. Their efficiency and compactness enable designers to reduce system footprint while maintaining high reliability in temperature-variable environments.

Packaging
Available in protective tray packaging for secure handling and automated assembly.

Frequently Asked Questions
Question: What derating is required at high temperatures?
Answer: Output current reduces above 60°C per manufacturer guidelines. Refer to the datasheet for derating curves.

Question: Can both outputs be loaded simultaneously?
Answer: Yes, the converter delivers full 100mA on both channels concurrently.

Question: Is this suitable for medical devices?
Answer: Yes, for commercial-grade (ITE) medical equipment where 500V isolation meets safety requirements.

Question: How does remote on/off functionality work?
Answer: A TTL-compatible signal enables/disables outputs without disconnecting input power.
