对于为笔记本电脑提供大电流的DC/DC补偿变换器,高效率很重要的。高效率可延长电池寿命,降低温升。一种使用外接MOSFET的低功耗同步整流器,它的效率就很高。然而,在使用同步整流器时必须特别小心。如果设计不当,在高端MOSFET与低端MOSFET同时
High efficiency is important for DC / DC compensation converters that provide high current to laptops. High efficiency extends battery life and reduces temperature rise. A low-power synchronous rectifier using an external MOSFET is very efficient. However, special care must be taken when using synchronous rectifiers. If not properly designed, high-side MOSFET and low-side MOSFET at the same time
