Isolated power supplies transfer power from one circuit to another without a direct connection between the two circuits. Power isolation protects electronic loads and equipment operators from exposure to high voltages. Power isolation also prevents ground loops, which produce parasitic currents that can disrupt the output voltage regulation and can introduce galvanic corrosion of the conducting traces. Isolated power supplies are routinely utilized in industrial, consumer, and telecom applications concerned with the protection of sensitive loads and the long-term reliability of the equipment.
Although an isolated power supply is more complex than a non-isolated power supply, it must still fit into a small space and perform with high efficiency. Our Rainier portfolio of isolated DC-DC and AC-DC converters and controllers deliver smaller solution sizes with smaller BOMs. Our patented technology eliminates the optocoupler from the feedback path, saving 30% of the typical board space required and up to 50% off the BOM. Industry-leading features include:
- Wide input voltage ranges
- High-efficiency operation
- Small packaging
- No-opto technology
- Adjustable switching frequencies
