We are excited to announce the expansion of our family of high isolation Push-Pull transformers with the release of the high frequency PAG6356 series, specifically developed for the TI SN6507. Our versatile EP7 platform, with extended creepage in a compact package size (13x10x12.5mm) has been selected to once again to provide reinforced insulation and up to 1000Vpk voltage rating. This time, the selection of a high frequency material and winding design supports a switching frequency up to 2MHz for a power delivery up to 10W.
The unique feature of this series is the 21V-uSec volt-second (ET) rating based on 1MHz switching frequency, suitable for a input voltage up to 60V. Different turns ratio’s are available, to deliver 3.3V to 15V output from a 24V to 36V input range, with 5000Vac electrical isolation, required for a range of industrial and automotive applications.
Many of our existing Push-Pull transformers have a ET rating that is appropriate for an input voltage in the range of 5V. Those, with a high ET rating, are often based on a relative low switching frequency which needs to be derated at higher switching frequency to avoid core loss and temperature rise issues. The PAG6356 is a market first in providing both a ET rating appropriate for higher input voltage that is based on the frequency range of the TI SN6507. This allows the user to benefit from the magnetic size reduction the comes with high switching frequencies, particular when selecting SiC power devices for enhanced system efficiency.

We have collaborated with TI to design our PAG6356 series in a way that benefits from the variable duty feature of their SN6507. Unlike other fixed duty cycle Push-Pull transformer drivers, which drops a ET across the primary winding that is proportional to the input voltage, the SN6507 implements a Duty Cycle Control (DCC) feature where the duty cycle is dynamically adjusted to compensate for the input voltage variation. This avoids the effects of an increase flux swing and additional core loss/temperature rise that are a feature of fixed duty Push-Pull drivers and increasing input voltages. This, along with the specially selected core material and winding design, allows the PA6356 series to support both higher input voltages and higher switching frequencies.
