The ET Max is calculated to limit the core loss and temperature rise at 200KHz based on a bipolar flux swing of 210mT Peak. This value needs to be derated for higher frequencies using the temperature rise calculation to remain with operating temperature range. 2. A. To calculate total copper loss (W), use the following formula: Copper Loss (W) = Irms_Primary[2] * DCR_Primary + Irms_ Secondary[2] *DCR_Secondary - B. To calculate total core loss (W), use the following formula: - Core Loss (W) = 2.31E-11* (Frequency in kHz)[ 1.68] *(210 * [ET/ET Max])[2.55] - Where ET is the applied Volt Second, ET Max is the rated Volt Second for 210mT flux swing Temperature Rise (°C) = 130 * (Core Loss(W) + Copper Loss (W)) 3. 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. 4. Creepage and clearance is in accordance with IEC 61558-1 and IEC61558-2-16 for reinforced insulation to a working voltage of 300Vrms (for basic insulation to a working voltage of 800Vrms) based on material group III, pollution degree 2, OVC II and 5000m altitude. 5. 850Vpk rated voltage is based on a positive partial discharge test (discharge < 10pC), in accordance with IEC60664 for basic insulation. In an application which requires a reinforced insulation barrier, a rated voltage of 650Vpk is defined and confirmed by - partial discharge testing. C.

It is compatible with a wide range push-pull drivers, such as the TI SN650x family, as part of a low cost solution for delivering isolation power from a low voltage source. 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 **==> picture [152 x 124] intentionally omitted <==** **----- Start of picture text -----**<br> VIN<br>VCC PH9384/PM2185<br>D1<br>V OUT<br>DRIVER<br>IC<br>D2<br>GND<br>**----- End of picture text -----**<br> PH9384.034NL has been certified by UL to comply with UL60950-1 2 edition with reinforced insulation for a working voltage up to 300Vac.
