rectifying efficiency

We build a synchronous rectifying switch power IC with high efficiency and good load characteristic following the requirements of the battery-powered portable equipments.

并具有良好大信号特性，以满足CPU、DSP和闪存等模块要求。根据电池供电便携式设备的要求，本论文设计了一款高效率、良好负载特性的双模式同步降压型开关电源IC。

The technology of synchronous rectification is to replace rectifying diode with power MOSFET which has low turn-on resistance, so it can decrease the dissipation of rectifier circuit greatly, improve the efficiency of DC/ DC converter and meet the needs of low-voltage and large current rectifier.
