Product Overview
The PH9384NL series are high isolation power supply transformer drivers designed for fixed duty cycle Push-Pull topologies. They offer a cost-effective solution for delivering lower power (up to 3W) from low voltage sources. A typical application is an isolated RS-485/RS-232 power supply driver circuit, compatible with the Maxim MAX253 IC. The output voltage is determined by the input voltage and turns ratio, allowing for a variety of output voltages. The PH9384.034NL model is UL60950-1 2nd edition certified with reinforced insulation for up to 300Vac working voltage, featuring 7mm creepage and 3000Vrms isolation voltage. The rest of the PH9384.XXXNL series comply with reinforced insulation requirements.
