IDT ZSPM9060DrMOS大电流高频电源功率级解决方案
摘要:IDT公司的ZSPM9060是新一代全优化超小型MOSFET和驱动器功率级解决方案,集成了驱动器IC,两个功率MOSFET和自举肖特基二极管,用于大电流高频同步降压DC/DC转换器.器件基于Intel® 4.0 DrMOS标准,电流高达60A,三态3.3V PWM输入驱动器,优化系统效率大于93%,和通常的分立解决方案相比,节省面积72%,主要用在高性能游戏主板,刀形服务器,台式计算机,工作站,大电流DC/DC点负载转换器和小型电压稳压器模块.本文介绍了ZSPM9060主要特性和优势,框图和应用电路,以及ZSPM8060-KIT评估板开环主要指标,电路图,材料清单和PCB设计图.
The ZSPM9060 is IDT’s next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, high-frequency, synchronous buck DC-DC applications. The ZSPM9060 integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6mm package.
With an integrated approach, the complete switching power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). The ZSPM9060 uses innovative high-performance MOSFET technology, which dramatically reduces switch ringing, eliminating the need for a snubber circuit in most buck converter applications.
