Gmunden, January 19 th , 2022 - The new RA3 range of DC/DC converters is available from
RECOM, designed to power IGBT, Si, SiC and GaN gate drivers.

RECOM has added to its range of low-cost, unregulated DC/DC converters with the RA3 series of 3W SMD parts which are designed to provide the optimum voltages for semiconductor switch gate drivers. Variants are available with outputs of single 8V, 9V, or dual +7/-1V, +15/-3V, and +20/-5V. These  values  cover  the  requirements  of  IGBTs,  silicon  MOSFETs  and  the  latest  silicon  carbide MOSFETs  and  GaN  HEMT  cells.  The  parts  have  5.2kV/  1  minute  functional  isolation  and  hold UL/IEC/EN 62368-1, CAN/CSA-C22.2 No 62368-1 certification, along with EN 61204-3 compliance. EMI EN 55032 class ‘A’ level is met without extra filtering and class ‘B’ requires just a simple LC filter. The 3W available suits not only large IGBTs but also other Si, SiC, and GaN devices when switched at high frequency.

Input voltages available are +5V, +12V, and +24V with +/-10% tolerance, and efficiency is typically better than 80%. Isolation capacitance is less than 10pF for high immunity to the fast, high voltage switching edges seen in high-side drivers, particularly with the wide band-gap technologies of SiC and GaN. Operating temperature range is -40°C to +85°C without derating (80°C for 1V, 8V, and 9V output parts).

The  RA3  series  is  surface-mount  with  ‘land  grid’  style  terminations  and  has  dimensions  of  just 23.4mm x 15mm x 8.5mm, giving 35% reduction in footprint and 60% reduction in volume compared with competitor parts. The surface mount format with wide spacings enables the necessary high isolation to be achieved on a customer’s PCB between the DC/DC output pins and other circuitry, with connection to just the top layer. The enclosed format and wide temperature range of the RA3 series suits harsh environments such as seen in renewable energy, solar inverters, induction heating, telecom, EV battery chargers, and motor drives.

Samples and OEM pricing are available from all authorized distributors or directly from RECOM. RECOM’s Product Manager, Matthew Dauterive, comments, “We have worked closely with leading manufacturers  of  wide  band-gap  devices  to  ensure  that  these  DC/DCs  provide  the  optimum performance  for  the  latest  generations  of  their  products.  They  are  also  significantly  smaller  and require fewer external components than other solutions on the market, making them easier to design in.”
