~~es~~|| 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_Primary[2] * DCR_Primary + Irms_Secondary[2] *DCR_Secondary - 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 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. PH9385.011NL becomes PH9385.011NL **T** ). Pulse complies to industry standard tape and reel specification EIA481. 6. The “NL” suffix indicates an RoHS-compliant part number. 7. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias voltage applied between primary and secondary windings. **==> picture [528 x 231] intentionally omitted <==** **----- Start of picture text -----**

_Toroid Platform SMD_ ## Isolation Power Transformers ## 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. **==> picture [263 x 172] intentionally omitted <==** **----- Start of picture text -----**

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. |For More Information|For More Information||||| |---|---|---|---|---|---| |**Pulse Worldwide**|**Pulse Europe**|**Pulse China Headquarters**|**Pulse North China**|**Pulse South Asia**|**Pulse North Asia**| |**Headquarters**|Pulse Electronics GmbH|Pulse Electronics (ShenZhen) CO., LTD|Room 2704/2705|3 Fraser Street|1F., No.111 Xiyuan Rd| |15255 Innovation Drive Ste 100|Am Rottland 12|D708, Shenzhen Academy of|Super Ocean Finance Ctr.|0428 DUO Tower|Zhongli City| |San Diego, CA 92128|58540 Meinerzhagen|Aerospace Technology,|2067 Yan An Road West|Singapore 189352|Taoyuan City 32057| |U.S.A.|Germany|The 10th Keji South Road,|Shanghai 200336||Taiwan (R.O.C)| |||Nanshan District, Shenzhen,|China||| |||P.R.
