Datasheet

Vishay has announced a versatile new planar transformer designed for switchmode power supply (SMPS) applications, including flyback, forward, push-pull, and half-bridge converters. Delivering a high level of flexibility, the new Vishay Sfernice PLAC 100 is user-configurable with software supplied by Vishay, which allows designers to adapt the transformer to a wide range of applications by setting the power supply type and desired level of input voltage, output voltage, power, and frequency.

Once these variables are entered, the software does the rest of the work, automatically determining the appropriate configuration and determining which outputs should be connected to obtain the best performance.

Typical applications for the PLAC 100 will include military, avionic, and medical systems, where its user configurability will save on engineering resources, speed time to market, and reduce sourcing and inventory costs by allowing a single component to cover a wide range of applications and power values.

The frequency range for the PLAC 100 is 50 kHz to 400 kHz. The transformer can handle up to 220 W. SMD and through-hole versions are available, with an operating temperature range of − 55 °C to + 125 °C.
