Notes:

1. The ET Max is calculated to limit the core loss and temperature rise at 200KHz based on

a bipolar ﬂux swing of 180mT Peak.

C. To calculate temperature rise, use the following formula:

Temperature Rise (°C) = 100 * (Core Loss(W) + Copper Loss (W))

2. For Push-Pull topology, where the voltage is applied across half the primary winding 4. The AEC-Q200 temperature and humidity operational life testing was completed using

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 dielectric strength test of 4000Vdc.

5. Optional Tape & Reel packing can be ordered by adding a “T” suﬃx to the part number

(i.e. PH9385.011NL becomes PH9385.011NLT). 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_Second- 6. The “NL” suﬃx indicates an RoHS-compliant part number.

B. To calculate total core loss (W), use the following formula:

Core Loss (W) = 3.93E-10 * (Frequency in kHz)^1.7* (180 * [ET/ET Max])^2.17

Where ET is the applied Volt Second, ET Max is the rated Volt Second for 180mT ﬂux

swing

bias voltage applied between primary and secondary windings.

8. The PM2155.XXXNLT part numbers are AEC-Q200 and IATF16949 certiﬁed. The mechani-

cal 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.

APPLICATION

PH9385.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 2.5W) from a low voltage source.

A typical implementation would be an isolated RS-485 power supply driver circuit, the design is compatible with the

MAXIM™ MAX253 IC. Other IC’s include Texas SN6501 UCC2808, Analog ADuM4070, ADuM447x.

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. This range can be extended by

implementing diﬀerent topologies such as forward or bridge and can be used with controllers oﬀered

by diﬀerent IC vendors for a number of diﬀerent applications.
