Ultra-compact Regulated 1W and 3W DC-DC Converters

The TRN Series from Traco Power is a new generation of ultra-compact 1- to 3-Watt, fully-regulated and isolated dc-dc converters in SIP or SMD package.

An optimized efficiency and thermal management enables a package volume of only about 1 cm3. The high performance converters provide an I/O isolation of 1600Vdc and a 2:1 input voltage range.

The low voltage input range extends from 4.5- to 13.2-Vdc to cover the nominal voltages of 5-, 9-, and 12-Vdc. The output voltage regulation is within 1.2% of nominal set voltage over the entire input range and from 0 to 100% load, minimum load is not required.

The outputs are permanently short circuit proof. The converters reliably operate in environment temperature range of -40°C to 90°C with 1 Watt or up to 65°C with 3 Watts of output power.

Models are available with 4.5- to 13.2-Vdc, 9- to 18-Vdc, 18- to 36-Vdc and 36- to 75-Vdc input voltage ranges and output voltages of 3.3, 5.0, 12, 15, 24, ±5.5, ±12 and ±15 Vdc.
