Compact push pull transformer driver PULSE PH9384.011NLT suitable for isolated power supply designs
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.
