IL1203S

The XP Power IL1203S is a 2-watt isolated DC-DC converter from the IL Series, designed for commercial ITE applications. It provides a regulated 3.3V output at 400mA from a nominal 12V input (10.8V to 13.2V range). Key electrical characteristics include a typical efficiency of 72%, line regulation of 1.2% per 1% input change, load regulation of ±10%, and setpoint accuracy of ±3%. Output ripple and noise is limited to 150 mV pk-pk maximum (20 MHz bandwidth). The converter offers 1000 VDC input-to-output isolation (optional 3000 VDC -H option) with isolation resistance of 1 GΩ and typical isolation capacitance of 60 pF. It operates over a -40°C to +85°C temperature range and is convection-cooled. The device is housed in a non-conductive black plastic case (UL94V-0) with epoxy potting (UL94V-0) and features solder-coated pins. The package is a 4-SIP through-hole module measuring 11.7mm x 7.5mm x 10.2mm and weighing 1.8 grams. The switching frequency is variable, typically 70 kHz. The converter can operate with no load but may not meet all specifications under that condition. Maximum capacitive load is 470 μF.
