REFACDC034 - Reference Design

Built-in SiC MOSFET Isolation Fly-back Converter QR method Output 48 W 24 V

The BM2SCQ123T-EVK-001 evaluation board outputs 24 V voltage from the input of 300 to 900 Vdc. The output current supplies up to 2.0 A. The BM2SCQ123T which is quasi-resonant method DC/DC converter IC built-in 1700 V SiC MOSFET (Silicon-Carbide) is used.

  • The BM2SCQ123T contributes to low EMI by soft switching in quasi-resonant method.
  • The integrated 1700 V 4 A SiC MOSFET contributes to ease of power supply design. Built-in burst mode reduces power loss at light loads.
  • The BM2SCQ123T is a ranked product that guarantees a long-term supply for the industrial equipment market.
