SMD Transformers

The heart of any DC/DC converter is the transformer. RECOM offers stand-alone, compact SMD transformers for low-wattage power supply applications. They can be driven by one of our transformer driver ICs or by your own circuit.

Transformer characteristics must be matched to the driver and application, so to simplify discrete power supply design, RECOM also offers matched driver IC and transformer pairs that are pre-tested to verify correct operation.

The transformer selection listed below are for common isolated DC power applications and are normally available ex-stock. Full custom transformer solutions are available upon request at short notice.
