The PH9385.XXXNL series from Pulse Electronics is a range of high isolation power supply transformer drivers designed for fixed duty cycle Push Pull topologies. These SMD toroidal transformers offer a cost-effective solution for delivering lower power (up to 2.5W) from a low voltage source. They are suitable for applications such as isolated RS-485 power supply driver circuits and are compatible with ICs like Maxim MAX253, Texas SN6501, UCC2808, and Analog ADuM4070, ADuM447x. The output voltage is determined by the input voltage and turns ratio, with options to extend the range through different topologies like forward or bridge converters.

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%.
2. The AEC-Q200 temperature and humidity operational life testing was completed using a dielectric strength test of 4000Vdc.
3. Continuous isolation voltage confirmed by 125C/1000hrs accelerated aging with the bias voltage applied between primary and secondary windings.
