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. PH9085.012NL becomes PH9085.012NLT). Pulse complies to industry

standard tape and reel speciﬁcation EIA481.

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

Toroid Platform SMD

Application

PH9085NL 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 2W) 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.
