750V, 45mΩ, 4-pin THD, Trench-structure, SiC-MOSFET
SCT4045DR은 어플리케이션의 소형화 및 저소비전력화에 기여하는 SiC MOSFET입니다. 패키지로는, SiC MOSFET의 특징인 고속 스위칭 성능을 최대화할 수 있는 드라이버 소스 단자를 탑재한 패키지를 채용하였습니다.
로옴의 제4세대 SiC MOSFET
SCT4 시리즈는 단락 내량 시간을 손상시키지 않고, 업계 최고 수준의 저 ON 저항을 실현한 제4세대 제품입니다. 본 시리즈는 기존품 대비 ON 저항을 약 40%, 스위칭 손실을 약 50% 저감하였습니다. 또한, 게이트 - 소스 전압은 취급이 쉬운 15V에도 대응하여, 어플리케이션 설계의 편의성이 향상됩니다.

- Industrial 3.6kW Totem Pole PFC Application EVK
Various applications are equipped with AC/DC functions, and the Totem Pole PFC topology is the standard circuit.The TPPFCSIC-EVK-301 implements a single-phase AC/DC conversion stage in Totem Pole PFC topology. Key components are ROHM Gen.4 SiC MOSFETs (SCT4045DR) as the main high-frequency switching elements, as well as the BM61S41 single-channel isolated gate driver IC. In addition, SJ MOSFETs and auxiliary power supply, among other components from ROHM, were utilized to create a high-performance AC/DC circuit for single-phase operation.TPPFCSIC-EVK-301 reaches up to 98.5％ efficiency at 230Vac.If this Totem Pole PFC reference design is coupled with a secondary stage of comparable efficiency, it becomes possible to achieve the 80+ Titanium target efficiency of power supply products. Moreover, this contributes to enhancing the Annual Performance Factor (APF) of air conditioners.
This reference design consists of two boards. Each is shown below.
