Vishay Intertechnology has expanded its portfolio of power transformers with the introduction of the IFBT series of surface-mount flyback transformers for converter applications.
The series comprises 17 devices designed for flyback converter topologies, with input voltage ranges from 26V to 72V at 250 kHz. Isolation is rated at 1,500 VRMS for 60 seconds between primary and bias windings to the secondary, while output voltages span 1.8V to 24V and output currents range from 0.5A to 9.0A. Inductance values vary from 35.0 µH to 75.0 µH, and devices operate across temperatures from -40°C to +125°C.
The IFBT series is engineered for 6W and 30W Power over Ethernet designs and isolated DC/DC converters up to 30W. Target application sectors include LED drivers in automotive lighting, power generation and distribution systems, industrial drives and automation, building controls, consumer devices, telecommunications equipment, and medical instrumentation. Open construction allows for winding modifications to meet specific customer requirements.
Samples and production quantities are available with lead times of 10 to 12 weeks. Vishay’s RoHS-compliant devices are manufactured in Malvern, Pennsylvania.
