The applied ET may need to be further derated for higher frequencies based on the<br>temperature rise which results from the core and copper losses<br>A. To calculate total copper loss (W), use the following formula:<br>Copper Loss (W) = Irms_Primary[2]* DCR_Primary + Irms_Secondary[2]*DCR_Secondary<br>B. To calculate total core loss (W), use the following formula:<br>Core Loss (W) = 6.74*10[-8 ]* (Frequency in kHz)[1.38]* (180 * [ET/ET Max])[2.864]<br>3.

Rated voltage is based on a positive partial discharge test (discharge < 10pC) for the pro-<br>file shown in page 3, in accordance with IEC60664 for basic insulation. In an application<br>which requires a reinforced insulation barrier, a rated voltage of 1200Vpk is defined and<br>confirmed by partial discharge testing.|

- B. To calculate total core loss (W), use the following formula: Core Loss (W) = 6.74*10[[-8 ]] * (Frequency in kHz)[[1.38]] * (180 * [ET/ET Max])[[2.864]] Where ET is the applied Volt Second, ET Max is the rated Volt Second for 180mT flex swing 

- C. To calculate temperature rise, use the following formula: Temperature Rise (°C) = 93 * (Core Loss(W) + Copper Loss (W))

## **APPLICATION** 

PMT6397.XXXNL is a series of high isolation power supply transformer drivers. Intended to operate in a fixed duty cycle Push Pull topology, it is a part of a low cost solution for delivering lower power (up to 3W) from a low voltage source. A typical implementation would be an isolated automotive power supply driver circuit, the design is compatible with the TI SN6501-Q1, along with many other automotive grade push pull drivers. A schematic diagram for the Push Pull converter topology is given below.

The 1:3 ratio ratio is intended to<br>deliver up to 15V from a 5V source. Other turns ratios can be made available on request.<br>**----- End of picture text -----**<br>


The distinguishing feature of the PMT6397 series is the segmented winding on the toroidal core. In addition to providing the reinforced insulation, the triple insulated wire in this winding construction provides enhanced electrical isolation, offering up to 1500Vpk rated voltage, making it suitable for high battery voltage automotive applications.
