C-MAC MicroTechnology's 225°C DC-DC converter is first product from CISSOID partnership

This product incorporates C-MAC’s high temperature microcircuit integration technology which provides the highest level of reliability for extended temperature applications. This solution will be aimed initially at down-well applications in the Energy market. In view of this, the product is packaged in a hermetic enclosure designed for small diameter bores (~1-2”) to fulfil the space envelope requirements of drilling tool manufacturers. A full range of package configurations will be available to suit the different requirements of Aerospace, Defence and other markets. The two companies combine a wealth of design and manufacturing experience in high temperature microelectronics and this product confirms their position at the forefront of high temperature microelectronic solutions.


Paul Hill, General Manager, of C-MAC MicroTechnology said ” The speed at which we have been able to bring forward this design is testament to C-MAC’s engineering expertise and our close relationship with CISSOID. Our BUCK DC-DC converter is the first of a range of products made possible by C-MAC’s high temperature technology and CISSOID’s high temperature active devices. We have shown that there is excellent synergy between our two teams and we look forward to a long and successful partnership. The combination of engineering skills between the two companies is highly complimentary. “

C-MAC will bring its extensive knowledge and manufacturing capability with high reliability chip and wire electronics technology to provide fully functional ‘Plug and Play’ modules integrating CISSOID’s established range of high temperature semiconductor products. The portfolio of products will operate within specification up to 225°C and will provide combinations of functions including voltage regulation, voltage references, analogue to digital converters, amplifiers, high voltage MOSFETs and drivers.

Tony Denayer, CEO of CISSOID said ”With the release of this module, CISSOID and C-MAC demonstrate once again that customers can rely on us for the actual and timely execution of our product roadmap. CISSOID’s high temperature roadmap for our VOLCANO family (DC-DC converters) as well as our TITAN family (drivers for electric motors in hybrid and electric cars) is in tune with the rapid evolution of the market’s needs, and we keep introducing those breakthrough products in a timely manner”.
