DC-DC Converters deliver 9 W of power in SIP-8 package.

Press Release Summary:

Occupying 0.3 in.² of board space, TMR 9 and TMR 9WI Series provide 2:1 and 4:1 input range, respectively, with single and dual regulated output voltages. Units feature flat switching transistor with extended dissipation surface. Combined with extra thermo-conducting potting compound, heat losses can be transferred to metal casing and dissipated to environment. Operating from -40 to +60°C at full load, converters provide 1,500 Vdc I/O-isolation, external On/Off, and short current protection.

Original Press Release:

Highest Power Density in a SIP Package

Wrentham, MA – Power Sources Unlimited, Inc. proudly announces the new TMR 9 and TMR 9WI Series which are the world’s first DC-DC Converter in a SIP-8 package that provides an isolated and regulated output voltage delivering 9 Watts of output power to our TRACO Power portfolio.

The TMR 9 Series achieves a 50% higher power density compared to conventional SIP converters and occupies only 2.0 cm2 (0.3 sq. in.) of board space. All models are equipped with a flat switching transistor with extended dissipation surface. Combined with an extra thermo-conducting potting compound the heat losses can be optimally transferred to the metal casing and dissipated to the environment. An operating temperature range of –40 to +60°C  at full load or up to +85°C with a 50% load de-rating these units reliably operate under extreme environmental conditions. Standard features include 1500VDC I/O-isolation voltage, external On/Off, short current protection and EMC according EN55022 class A. The converters are available with 2:1 (TMR 9) or 4:1 (TMR 9WI) input range and single and dual output voltages.

The very compact dimensions of these converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.

Pricing starts under $18 each in OEM quantities. Prototype quantities are available, stock to 2 weeks after receipt of order. PSUI is an ISO 9001:2008 North American Authorized Distributor for TRACO Power. All TRACO Power products are backed by a 3 year warranty.
