The maximum volt-usec rating limits the peak flux density to 3600 gauss when used in 2. Optional Tape & Reel packing can be ordered by adding a T suffix to the part bi-polar drive application with 200KHz. For unipolar drive applications or a bi-polar drive number (i.e. PH9384.012NL becomes PH9384.012NLT). Pulse complies to industry with 350kHz, a maximum volt-usec could be 60% of the listed value. For Push-Pull top- standard tape and reel specification EIA481. ology, where the voltage is applied across half the primary winding turns, the maximum 3. The NL suffix indicates an RoHS-compliant part number. volts-use needs to be derated by 50%.

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. V IN PH9384 V CC D1 VOUT DRIVER IC D2 GND 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. MAXIM is a registered trademark of Maxim Integrated Products.
