RA3 Series: 3W SMD Single and Dual Output DC/DC Converters Designed to Power IGBT, Si, SiC and GaN Gate Drivers

RECOM has expanded its range of low-cost, unregulated DC/DC converters with the new RA3 series of 3W SMD parts that are designed to provide the optimum voltages for semiconductor switch gate drivers. The new RA3 series is surface-mount with ‘land grid’ style terminations and has dimensions of just 23.4mm x 15mm x 8.5mm, giving a 35% reduction in footprint and 60% reduction in volume compared with competitor parts. The modules are available with input voltages of 5, 12, or 24VDC with single or dual asymmetric outputs to cover the latest Si, SiC, and GaN transistors.

These 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. Moreover, the compact SMD design ensures that the required board space is minimal - especially on multilayer PCBs.
