电源技术 SM发射机电源电压恒定的发射功率
Abstract: In battery-powered RF transmitters such as garage door openers and remote keyless entry for cars, as the battery drains,
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 低噪声,低压差稳压器的性能验证
 
In an increasing trend, telecommunications, networking,audio and instrumentation require low noise power supplies.In particular, there is interest in low noise, lowdropout linear regulators (LDO). These components powernoise-sensitive circuitry, circuitry that contains noisesensitiveeleme ...
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 ...
