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.

swing

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.

6. The PM2180.XXXNL part numbers are AEC-Q200 and IATF16949 certiﬁed. The mechanical

dimensions are 100% tested in production but do not necessarily meet aproduct capability

index (Cpk) >1.33 and therefore may not strictly conform to PPAP.

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

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:

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

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.
