Highest power density DC-DC converter in a SIP package

Power Sources Unlimited (PSU) has announced availability of the new Traco Power TMR 9 and TMR 9WI Series which are the world’s first DC-DC converters in a SIP-8 package that provides an isolated and regulated output voltage delivering 9W of output power, says the company. The TMR 9 Series achieves a 50% higher power density compared to conventional SIP converters and occupies only 2cm2 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 –40C to +60C at full load or up to +85C 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 exceptionally compact dimensions of the converters make them an ideal solution for many space critical applications in communication equipment, instrumentation and industrial electronics.
