Notes:

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

for 130mT ﬂux swing

a bipolar ﬂux swing of 130mT Peak.

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

Temperature Rise (°C) = 154 * (Core Loss(W) + Copper Loss (W))

4. The AEC-Q200 temperature and humidity operational life testing was completed using

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. PH9384.012NL becomes PH9384.012NLT). Pulse complies to industry standard tape

and reel speciﬁcation EIA481.

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

6. The “NL” suﬃx indicates an RoHS-compliant part number.

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

Core Loss (W) = 2.72E-12 * (Frequency in kHz)^2.43*(130 * [ET/ET Max])^2.5

Where ET is the applied Volt Second, ET Max is the rated Volt Second

7. The PM2185.XXXNL 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

PH9384NL 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.

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. PH9384.034NL has been certiﬁed by UL to comply with UL60950-1 2 edition with reinforced insulation for

a working voltage up to 300Vac. 7mm creepage and 3000Vrms isolation voltage is guaranteed to meet this requirement. The 4000Vrms Isolation (550Vrms

continuous) capability is in excess of this and applies to applications where just function insulation/galvanic isolation are required. The remainder of the

PH9384.XXXNL series was not included in the UL certiﬁcation but are fully complaint with the requirements for reinforced insulation.
