About DC-DC Converters

DC-DC converters regulate voltage levels in electronic systems, enabling stable operation when input sources fluctuate. Isolated modules like this Cosel unit electrically separate input and output circuits, preventing ground loops and enhancing safety in sensitive equipment. They are fundamental in protecting downstream components from voltage spikes and noise.

In modern electronics, compact board-mount converters enable miniaturization without sacrificing power integrity. Their efficiency and thermal management capabilities make them indispensable for applications ranging from renewable energy systems to portable devices, where space and reliability are paramount.

FAQs

Q: What derating is required at high temperatures?
A: Above +70°C, power output decreases linearly to 50% at +85°C ambient. Refer to the datasheet for derating curves.

Q: Is this suitable for medical devices?
A: While designed for ITE applications, it lacks medical certifications. For medical-grade DC-DC, consult PCX for alternative Cosel solutions.

Q: How does remote On/Off function work?
A: Apply TTL logic (high = on, low = off) to the control pin. An open circuit defaults to enabled state.

Q: Can both outputs deliver 100mA simultaneously?
A: Yes, total power remains within 3W (15V×0.1A + 15V×0.1A = 3W).

Q: What safety certifications does it hold?
A: Complies with IEC/EN 62368-1 (ITE equipment) and UL 62368-1 standards.

Q: Are evaluation samples available?
A: PCX offers sample requests for qualified projects—contact our support team.
