Product Overview
The PH9185.XXXNL and PM2190.XXXNL are high isolation power supply transformer drivers from the EP7 Platform SMD series. Designed for fixed duty cycle Push Pull topologies, these transformers offer a cost-effective solution for delivering lower power (up to 3W) from low voltage sources. A typical application includes isolated RS-485/RS-232 power supply driver circuits, with compatibility for the MAXIM MAX253 IC. The design features reinforced insulation, 8mm creepage, and 5KVrms isolation, meeting stringent safety standards. The output voltage is determined by the input voltage and turns ratio, allowing for a variety of output voltage selections.
