OREANDA-NEWS. May 21, 2015. TDK Corporation announces the successful development of the CCG series of isolated type DC-DC converters to be marketed under the TDK-Lambda brand. TDK-Lambda Corporation will start accepting orders for the new product from June, and shipping will begin in July 2015.

The CCG series products are onboard type DC-DC converters with a wide input range, based on a 1 x 1 inch footprint. The CCG30 model realizes a 30 watt output rating in a form factor of only one square inch, thereby helping to reduce control board space requirements. The input voltage range is 9 to 36 or 18 to 76 VDC, making the products suitable for use with battery powered equipment and control boards. In cases where separate versions (12 VDC / 24 VDC) of earlier products such as the CC-E series were used, it is now possible to unify converter selection by adopting the wide-range CCG series, resulting in better design flexibility and contributing to higher productivity.

The CCG series achieves an industry leading power density rating, providing up to 30 watts of power from a mounting footprint of only one square inch. Use of the new converters therefore reduces footprint requirements and enables higher mounting density on control boards for various types of equipment.

* As of May 2015, according to TDK data

Main applications

Control boards in ICT equipment (base stations, servers), semiconductor manufacturing equipment, measuring equipment, general industrial equipment, etc.

Main features

  • Compact dimensions: 30 W output from 1 x 1 inch footprint
    * Among the smallest in the industry, about 50% less than comparable earlier products
  • Wide input voltage range: 9 to 36 VDC and 18 to 76 VDC input types available
    * About twice the input voltage range of comparable earlier products
  • Six-sided shielded construction for noise protection: In addition to metal enclosure, PCB copper foil provides bottom shielding
  • High efficiency: 91% (CCG30-48-15S)
  • Wide ambient temperature range for operation: Usage in environments from -40°C to +85°C supported
  • 1,500 VDC Withstand voltage rating (1 minute): High input to output isolation contributes to enhanced safety
