As the performance of many handheld devices approachesthat of laptop computers, design complexity also increases.Chief among them is thermal management—how doyou meet increasing performance demands while keepinga compact and small product cool in the user’s hand?For instance, as battery capacities inevitably increase,charge currents will also increase to maintain or improvetheir charge times. Traditional linear regulator-based batterychargers will not be able to meet the charge currentand effi ciency demands necessary to allow a product torun cool. What is needed is a switching-based chargerthat takes just about the same amount of space as a linearsolution—but without the heat.

随着我国各种功能车辆及游艇事业的蓬勃发展。越来越多的各种通信设备、日常电器、精密仪器被应用其中。但也由此带来一些必然的问题：在移动应用的过程中如何保证其正常工作不受影响呢？首先要解决的就是电力问题。没有稳定的电力供应系统，所有车载设备的应用及使用寿命都将受到极大的影响。当前最好的解决方案当然是配置一套优良的UPS不间断电源系统。可是普通的UPS系统由于其针对的是普通商用或工业用途，其性能、特点都无法满足目前移动电源的需求的。
