## **Notes:** 

1. The maximum volt-usec rating limits the peak flux density to 3600 gauss when used in bi-polar drive application with 200KHz. For unipolar drive applications or a bi-polar drive with 350kHz, a maximum volt-usec could be 60% of the listed value. For Push-Pull topology, where the voltage is applied across half the primary winding turns, the maximum volts-use needs to be derated by 50%. 

   3. Optional Tape & Reel packing can be ordered by adding a “ **T** ” suffix to the part number (i.e. PH9185.012NL becomes PH9185.012NL **T** ). Pulse complies to industry standard tape  and reel specification EIA481. 

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

   5. Continuous isolation voltage confirmed by 125°C/1000hrs accelerated aging with the bias voltage applied between primary and secondary windings. 

2. The AEC-Q200 temperature and humidity operational life testing was completed using a dielectric strength test of 5000Vdc.

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.

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 2    edition, and CAN/CSA C22.2 nd NO. 60950-1-07 2   edition; and by TUV to comply with EN61558-1 and EN61558-2-16 with reinforced insulation nd 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.
