High-density DC/DC converter is first to reach 9W

The TMR9 Series consists of 27 models featuring 2:1 Input ranges of 9-18 / 18-36 / 36-75VDC and single or dual outputs from 3.3~24VDC. TRACO also has available in the same footprint a WI version with ultra-wide 4:1 input ranges of 9-36 / 18-75VDC. These converters reach a 50% higher power density compared to conventional SIP converters utilising a flat switching transistor with an extended dissipation surface and thermo conducting potting compound for optimised thermal transfer to the metal casing and dissipated to the environment.

These 9W converters operate up to 60°C at full load (85°C with a 50% load de-rating). With 1500 VDC I/O-isolation voltage, external On/Off, short current protection, no minimum load requirement and EMC according EN55022 class A, they are suitable power solutions for a wide range applications.
