Würth Elektronik Push-Pull Transformers for TI SNxx Drivers

Würth Elektronik WE-PPTI Push-Pull Transformers feature a small size that offers high performance and high isolation voltage of 2.5kV. WE-PP transformers for Texas Instruments SN6505 drivers feature a 120kHz to 480kHz frequency range and 1A current rating. SN6505 drivers are low noise, low electromagnetic interference (EMI) drivers for isolated power supplies in small packages. The SN6501 push-pull drivers are designed for small transformers used in a variety of applications, such as isolated interfaces or low-power LAN.
