深圳市联益微电子有限公司

深圳联益微公司推出LY2953A高性能超高效率降压芯片，IC采用BCD工艺，专为便携移动计算机、视频、通讯设备而设计的高效大功率电流型同步整流转换芯片，输入电压为4.75V～23V，输出电压为0.925V～20V，输出的连续负载电流为3A。LY2953A的内部振荡频率为340kHz、以保证对系统其他部分的EMI干扰；DC-DC转换效率高达95%，可以满足电源节能与持久工作要求。该芯片还具有软启动（时间可调）和逐周期过流、短路及过温保护功能。LY2953A内置两只MOs管，如图1所示。输出电压经外部电阻分压后，先由误差放大器放大，然后与内部检测到的上管峰值电流进行比较，其结果决定上管导通时间的占空比，而占空比变化又控制着输出电压变化，从而完成负反馈控制。应用于高端智能电子产品电源降压供电。
