Isolated DC/DC converters & modules

Simplify your isolated DC/DC design

parametric-filterView all products
Our portfolio of isolated bias supplies, modules and power converters combines high-density integrated-FET converters and integrated-transformer modules to reduce your BOM count and simplify your isolated DC/DC design. Transformer drivers with external transformers can provide a simple isolated power solution while the primary side regulated (PSR) flyback and Fly-Buck™ converter portfolios can be optimized for performance with an external transformer.

Modules    

Our isolated power modules increase performance and reduce solution size. Featured products include integrated transformer technology with certified isolation.

Converters

Easily generate one or more isolated positive and negative supplies using a small number of external components. An optocoupler is not required, and devices can be used for isolated applications.

Transformer drivers    

Our compact push-pull and LLC transformer drivers provide a simple, low-EMI, isolated power supply and are ideal for cost-constrained applications when compared to integrated isolated power solutions.

Power trends

Shrink your power solution, maximize efficiency

These unique solutions can shrink your power solution by as much as 80% and maximize efficiency in high-voltage industrial applications with high density. The 16-pin SOIC package measures 10.3 mm x 10.3 mm x 2.65 mm and offers 60% efficiency—twice that of competing devices of similar size—and twice the power density of comparative isolated power modules. Delivering 0.5 W in the new architecture improves reliability, enables a small BOM and simplifies board layout.
