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.

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

180mT ﬂux swing

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_

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

Temperature Rise (°C) = 90 * (Core Loss(W) + Copper Loss (W))

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

(i.e. PH9184.011NL becomes PH9184.011NLT). Pulse complies to industry standard tape

and reel speciﬁcation EIA481.

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

6. The temperature of the component (ambient plus the temperature rise) must be

within the stated operating temperature range.

Secondary²*DCR_Secondary

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

High Isolation Power Transformers

EP7 Platform SMD

Application

PH9184NL 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.

This transformer design conforms to UL60950-1 2 edition with basic insulation for a working voltage up to 300Vac.

3.2mm creepage and 3000Vrms isolation voltage is guaranteed to meet this requirement. The actual isolation and

creepage capability of the design exceeds these UL ratings.
