The XP Power IU4803SA is a regulated isolated DC-DC converter from the IU series. It accepts a wide 2:1 input voltage range of 36 to 72 VDC and provides a single output of 3.3 VDC at up to 500 mA, delivering 2 W of power. The converter features 1000 VDC input-to-output isolation and continuous short circuit protection with auto recovery.
Key electrical specifications include a line regulation of ±0.5%, load regulation of ±1% for a 25-100% load change, and ripple and noise of 80 mV pk-pk maximum (20 MHz bandwidth). The switching frequency ranges from 100 to 650 kHz. Efficiency is 71% typical. The device can drive a maximum capacitive load of 3300 µF.
The IU4803SA is designed for commercial ITE (Information Technology Equipment) applications and complies with UL62368-1 safety standards. It operates over a temperature range of -40°C to +85°C and is convection cooled. The converter is housed in an 8-SIP module with 5 leads, measuring 21.9mm x 9.2mm x 11.1mm, and is through-hole mountable with solder pin termination.
