High power density DC/DC converters provide 9W from a SIP-8 package

Powersolve has what is said to be the world’s first SIP-8 packaged DC/DC converter series to provide an isolated and regulated output voltage with up to 9W of output power.

Models in the Tracopower TMR9 series are available with 2:1 (TMR 9) or 4:1 (TMR 9WI) input ranges and cover nominal inputs of 12V, 24V and 48V DC. Single and dual output voltages of 3.3V to 24V DC are available within the range.

The converters feature a 50% higher power density compared to conventional SIP converters and can reliably operate up to 60°C environment temperature at full load or up to 85°C with a 50% load de-rating. This is because TMR 9 Series models are designed using a special design flat switching transistor with an extended dissipation surface. This, together with an extra thermo-conducting potting compound, allows the heat to be efficiently transferred to the metal casing and dissipated to the environment.

Key features include 1500 VDC I/O-isolation voltage, external On/Off, short current protection and EMC according EN55022 class A.
