DC DC Converters

1 W12 VDC input5 VDC outputisolated DC/DCSIP-4through-hole

IF1205S-1WR3 is a 1 W SIP isolated DC/DC module for converting a regulated 12 VDC rail to an isolated 5 VDC output at up to 200 mA.

Best for

  • Low-power isolated 5 V rails from 12 V systems
  • Digital circuits
  • Relay-drive and data-exchange circuits

Avoid if

  • Input voltage can exceed the stated 11.4 VDC to 12.6 VDC range
  • More than 1 W output power is required
  • High efficiency is a primary design requirement

Check before use

  • Validate 5 V output current does not exceed 200 mA
  • Apply derating above +71 °C ambient
  • Check external capacitor value and startup behavior
  • Confirm 3000 VDC isolation is suitable for the system
