IB0503XT-W75R3 is a compact 0.75 W isolated 5 V-to-3.3 V regulated DC/DC module for low-power board-level isolation.

Best for

  • Low-power isolated 3.3 V rails from a regulated 5 V source
  • Digital and low-frequency analog isolation
  • Relay-drive and data-interface circuits

Avoid if

  • Output current above 227 mA is required
  • The input source can exceed 5.25 V
  • Operation at high ambient temperature requires full 0.75 W output without derating

Check before use

  • Confirm minimum load requirement of 23 mA
  • Confirm PCB land pattern and 2.54 mm pin pitch
  • Check output capacitance and startup behavior
  • Validate isolation requirements for the end system
