Rohm Semiconductor has added the PrestoMOS MOSFETs to its range of high speed switching, high voltage resistance MOSFETs for power factor correction circuits in switching power supplies and main switch circuits. The MOSFETs have low trr characteristics for high speed switching, high efficiency and low loss, making it suitable for integrated power supply inverters, lighting, motor drivers, solar batteries, power conditioners, and high frequency bridge circuits. Using ion-based production technology and high voltage processes, the MOSFETs achieve low on-resistance and low Qg for greater inverter efficiency. The company claims that the MOSFETs' high speed trr body diode eliminates the need for an external fast recovery diode and consumes a small mounting area, thereby saving space.
