| 摘 要： | 传统的电池电源设计存在诸多弊端:低电压供电难,供电时间短,输出电压纹波较高,消耗电流大以及开关频率高时,效率低下。笔者以TI公司的充电泵TPS60210为基础,采用推挽拓扑结构,根据负载电流的大小,自动选择三种不同的工作模式(待机,连续频率及脉冲–跳跃),实现了低EMI、高转换效率的电池电源设计,减少了常规充电泵固有的高输出电压纹波,延长了电池寿命。

| Abstract: | With the traditional battery supply system, some performances cannot be achieved such as supplying at lower voltage or for long-time, lower ripple output voltage and lower current consumption at high switching frequency. A new charge pumps TPS60210 made by TI Corporation, which adopts the push-pull topology structure, can select three different work modes automatically according to output current and no inductors involved. The employment of the pump makes it possible to design a low EMI, high efficient, battery supply system, which can reduces the inherent and high ripple output voltage and increases the battery life. |
