IU4809SA Description

Short technical summary and product information.

The XP Power IU4809SA is a regulated, isolated DC-DC converter from the IU series, delivering a single 9V output at 222mA with 2W of output power. It accepts a wide 2:1 input voltage range of 36 to 72V DC, making it suitable for industrial and telecom applications where input rails vary.

 

Key electrical specifications include a typical efficiency of 78%, line regulation of ±0.5% over the full input range, and load regulation of ±1% for a 25-100% load change. Output ripple and noise are limited to 80mV pk-pk (20 MHz bandwidth), and the converter provides continuous short circuit protection with auto recovery. The switching frequency ranges from 100 to 650 kHz.

 

The IU4809SA is housed in an 8-SIP module with 5 leads, measuring 21.9mm x 9.2mm x 11.1mm, and is designed for through-hole mounting. It offers 1000VDC input-to-output isolation and operates over a -40°C to +85°C temperature range with convection cooling. The device is intended for ITE (commercial) applications and is designed to meet UL62368-1 safety standards.
