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 top-
ology, where the voltage is applied across half the primary winding turns, the maximum
volts-use needs to be derated by 50%.
2. Optional Tape & Reel packing can be ordered by adding a “T” suffix to the part
number (i.e. PH9384.012NL becomes PH9384.012NLT). Pulse complies to industry
standard tape and reel specification EIA481.
3. The “NL” suffix indicates an RoHS-compliant part number.

High Isolation Power Transformers
Toroid Platform SMD
Application
PH9384NL 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.
