Notes:
1. The ET Max is calculated to limit the core loss and temperature rise at 100KHz based on a
bipolar flux swing of 210mT Peak.
Core Loss (W) = 7.70E-13 * (Frequency in kHz)2.43 * (210 * [ET/ET Max])2.5
Where ET is the applied Volt Second, ET Max is the rated Volt Second for 210mT flux
2. For Push-Pull topology, where the voltage is applied across half the primary winding turns, swing
the ET needs to be derated by 50% for the same flux swing.
3. The applied ET may need to be further derated for higher frequencies based on the
temperature rise which results from the core and copper losses
C. To calculate temperature rise, use the following formula: Temperature Rise (°C)
= 340 * (Core Loss(W) + Copper Loss (W))
4. The AEC-Q200 temperature and humidity operational life testing was completed using a
dielectric strength test of 2750Vdc.
5. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias
voltage applied between primary and secondary windings.
A. To calculate total copper loss (W), use the following formula:
Copper Loss (W) = Irms_Primary2 * DCR_Primary + Irms_Secondary2*DCR_Secondary
B. To calculate total core loss (W), use the following formula:

Isolation Power Transformers
Toroid Platform SMD
Application
PH9085.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 2W) from a low voltage
source. A typical implementation would be an isolated RS-485/RS-232 power supply driver circuit, the design is
compatible with the MAXIM™ MAX253 IC.
A schematic diagram for the Push Pull converter topology is given below.

For a fixed 50% duty cycle mode of operation, the output voltage is simply determined by the input voltage and
turns ratio. So, with the available turns ratios, a variety of output voltages can be selected.
