Notes:
1. The ET Max is calculated to limit the core loss and temperature rise at 100KHz based on a
bipolar flux swing of 180mT Peak.
C. To calculate temperature rise, use the following formula: Temperature Rise (°C) =
90 * (Core Loss(W) + Copper Loss (W))
2. For Push-Pull topology, where the voltage is applied across half the primary winding
turns, 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
4. The AEC-Q200 temperature and humidity operational life testing was completed using a
dielectric strength test of 5000Vdc.
5. Optional Tape & Reel packing can be ordered by adding a “T” suffix to the part number
(i.e. PH9185.012NL becomes PH9185.012NLT). Pulse complies to industry standard tape and
reel specification EIA481.
A. To calculate total copper loss (W), use the following formula:
Copper Loss (W) = Irms_Primary2 * DCR_Primary + Irms_Secondary2*DCR_Secondary 6. The “NL” suffix indicates an RoHS-compliant part number.
B. To calculate total core loss (W), use the following formula:
Core Loss (W) = 4.40E-10 * (Frequency in kHz)1.67 * (180 * [ET/ET Max])2.53
Where ET is the applied Volt Second, ET Max is the rated Volt Second for 180mT flux
swing
7. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias
voltage applied between primary and secondary windings.
8. The PM2190.XXXNL part numbers are AEC-Q200 and IATF16949 certified.

APPLICATION
PH9185.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 RS-485/RS-232 power supply
driver circuit, the design is compatible with the MAXIM™ MAX253 IC.

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.
This transformer design has been certified by UL to comply with UL60950-1 2nd edition, and CAN/CSA C22.2 NO. 60950-1-07 2nd edition; and by TUV to comply
with EN61558-1 and EN61558-2-16 with reinforced insulation for a working voltage up to 400Vac 8mm creepage and 5000Vrms isolation voltage is guaranteed
to meet this requirement. The design also complies with the Pulse’s class F insulation system. PH9185.013NL was not included in the original UL/TUV certification
but is complaint. Cost reduced versions without UL/TUV certification available, please contact Pulse Electronics for more information.
