电源技术 DN465 超低功耗升压转换器
 
Industrial remote monitoring systems and keep-alivecircuits spend most of their time in standby mode. Manyof these systems also depend on battery power, so powersupply effi ciency in standby state is very important tomaximize battery life. The LT®8410/-1 high effi ciencyboost converte ...
电源技术 笔记本电脑的功率调节系统
 
Notebook and palmtop systems need a multiplicity ofregulated voltages developed from a single battery. Smallsize, light weight, and high efficiency are mandatory forcompetitive solutions in this area. Small increases inefficiency extend battery life, making the final productmuch more usab ...
电源技术 LTC1325电池管理IC的使用
 
For a variety of reasons, it is desirable to charge batteriesas rapidly as possible. At the same time, overchargingmust be limited to prolong battery life. Such limitation ofovercharging depends on factors such as the choice ofcharge termination technique and the use of multi-rate/multi-s ...
电源技术 LT1300和LT1301在功率DCDC转换器中的应用
 
The design of battery-powered equipment can often bequite challenging. Since few ICs can operate directly fromthe end-of-life voltage from a 2-cell battery (about 1.8V),most systems require a DC/DCconverter. The systemdesigner often has a limited area in which to place the DC/DC converter ...
电源技术 Circuitry for Single Cell Operation
 
Portable, battery-powered operation of electronic apparatushas become increasingly desirable. Medical, remotedata acquisition, power monitoring and other applicationsare good candidates for batteryoperation. In some circumstances,due to space, power or reliability considerations,it is pre ...
单片机编程 单片机控制的铅酸蓄电池充电电源
 为了有效地提升铅酸蓄电池的使用寿命，同时实现对充电过程的监控，设计出一种用单片机控制的36 V铅酸蓄电池充电电源。本电路采用反激式拓扑，连续电流工作模式，电源管理IC设计在电源的副边，由ELAN公司的EM78P258N单片机模拟，是用可编程器件模拟电源管理IC，实现智能电源低成本化的一次成功尝试，通过对单片机的软 ...
单片机编程 NXP P89LPC901单片机汽车起动保护控制器设计
在汽车发动机起动时，若发动机起动后起动机不能及时断电，将会烧毁起动机或损坏飞轮齿环；若变速器不在空档位置起动，则起动机的瞬间动力将使汽车位移，还可能引起交通事故和人身安全。为此介绍一种利用NXP P89LPC901单片机控制的汽车起动保护控制器，通过检测汽车起动开关、变速箱档位、发动机转速，实现对汽车发动机起动 ...
