The ET Max is calculated to limit the core loss and temperature rise at 100KHz based on a C. To calculate temperature rise, use the following formula: Temperature Rise (°C) = bipolar flux swing of 180mT Peak. 90 * (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 a turns, the ET needs to be derated by 50% for the same flux swing. dielectric strength test of 5000Vdc. 3. The applied ET may need to be further derated for higher frequencies based on the 5. Optional Tape & Reel packing can be ordered by adding a “T” suffix to the part number temperature rise which results from the core and copper losses (i.e. PH9185.012NL becomes PH9185.012NLT). Pulse complies to industry standard tape and A. To calculate total copper loss (W), use the following formula: reel specification EIA481. 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: 7.

High Isolation Power Transformers EP7 Platform SMD 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. A schematic diagram for the Push Pull converter topology is given below. V IN V PH9185 CC D1 V OUT DRIVER IC D2 GND 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. MAXIM is a registered trademark of Maxim Integrated Products.
