IU0503SA Description

Short technical summary and product information.

The XP Power IU0503SA is a regulated single-output isolated DC-DC converter from the IU Series. It accepts a wide 2:1 input voltage range of 4.5V to 9.0V and delivers a stable 3.3V output at up to 500mA, with a total output power of 2W. The module provides 1000VDC input-to-output isolation (optional 3000VDC) and features continuous short circuit protection with auto recovery.

 

Key electrical characteristics include a typical efficiency of 67%, line regulation of ±0.5%, load regulation of ±1% (25-100% load change), and a setpoint accuracy of ±2%. Ripple and noise are limited to 80 mV pk-pk maximum at 20 MHz bandwidth. The converter operates over a -40°C to +85°C temperature range and is convection cooled.

 

The IU0503SA is housed in an 8-SIP module with 5 leads and a through-hole mounting style. Its compact dimensions are 21.9mm x 9.2mm x 11.1mm. The module is designed for ITE (commercial) applications and carries a 3-year warranty.
