Fairchild FEB219开关电源方案

Fairchild公司的FPP06R001高效率整流模块,内置了非常低导通电阻的MOSFET以及极好的栅极驱动器. FPP06R001可用在正激/桥式转换器PWM变压器的次级,在输出级提供5V到12V的大电流整流.因此可广泛应用在互联网服务器和通信系统的电源.本文介绍了FPP06R001的主要特性以及模块方框图, 正激转换器应用电路, 异步HB转换器应用电路和全桥转换器应用电路以及FPP06R001评估板的电路图和所用元件清单(BOM).

The FPP06R001 is one product in the Power-SPMTM family that Fairchild has newly developed and designed to be most suitable for more compact and more efficient synchronous rectification applications such as internet server power supplies and telecom
system power supplies. For higher efficiency, it includes built-in very low RDS(ON) MOSFETs. In addition, it includes the superior gate driver that supports higher driving capability to be more suitable for these low RDS(ON) MOSFETs. This Power-SPM device can be used in the secondary side of the PWM transformer of forward/bridge converter to provide high current rectification at output voltages ranging from 12 Volts down to 5 Volts.

With this product, it is possible to design the secondary side of power supply systems with reduced parasitic elements resulting in minimized voltage spike and EMI noise.
