The Traco Power TRN 1-1221 is a 1-watt isolated DC/DC converter from the TRN 1 series. It delivers dual regulated outputs of +5V and -5V, each rated at 100mA maximum current. The converter operates from a nominal 12V input with a 9-18V range and achieves 79% typical efficiency.
This module provides 1600 VDC input-to-output isolation and includes short circuit protection (SCP). It is designed for commercial ITE (Information Technology Equipment) applications and operates over a -40°C to +90°C temperature range without derating.
The TRN 1-1221 is housed in a compact 5-SIP through-hole package measuring 11.9mm x 7.7mm x 11.0mm. Its fully regulated outputs and small footprint make it suitable for space-constrained designs requiring isolated bipolar supplies.
