RA3 DC/DC Converters

RECOM’s 3W SMD Single- and Dual-Output RA3 series DC/DC Converters for Si, SiC and GaN Power Transistor Gate Drivers

RECOM’s RA3 series features 3-watt DC/DC converters which are especially designed to power transistor gate drivers. The modules are available with input voltages of 5, 12, or 24 VDC with single or dual asymmetric outputs to cover the latest Si, SiC, and GaN transistors on the market today. The compact SMD design ensures that required board space is minimal – especially on multilayer PCBs. The modules offer a robust 5.2kVDC/1min isolation and an isolation capacitance less than 10pF. The operating temperature range of -40C to +85°C at full load meets harsh environmental requirements for renewable energy such as solar inverters, induction heating, telecom, EV battery chargers, and motor drives.

Features

  • 3W isolated DC/DC converter
  • High 5.2kVDC/1min isolation
  • Wide operating temperature range: -40°C to +85°C
  • Ideal for IGBT/Si/SiC/GaN gate drive power
  • IEC/EN/UL CSA 62368-1 certified
  • Less than 10pF isolation capacitance
  • Compact DIP16 SMD package
