The PW4556 series of devices are highly integrated Li-Ion and Li-Pol linear chargers targetedat small capacity battery for portable applications. It is a complete constant-current/ constantvoltage linear charger. No external sense resistor is needed, and no blocking Diode is required dueto the internal MOSFET architecture. It can deliver up to 300mA of charge current (using a goodthermal PCB layout) with a final float voltage accuracy of ±1%. The charge voltage is fixed at 4.2V or4.35V, and the charge current can be programmed externally with a single resistor. The chargerfunction has high accuracy current and voltage regulation loops and charge termination

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking Diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2µA. The PW4055 can be put into shutdown mode, reducing the supply current to 25µA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage

如何正确导入Spice模型方法一、将模型文件粘在当前的图纸上，方法见图：步骤1：复制模型文件（米源于OrCAD PSpice Model）步骤2：将复制的文件复制到下图所示位置步骤3：点击上面框图中的OK，将文件粘贴在纸面上，然后从文件中拖一个三极管出来，将名字改成一样即可。方法二、如有*.1ib的库文件，比如PSPICE的日本晶体管库jbipolar.lib，将该文件考到LTC LTspicelV\lib\sub目录中。然后按图操作：方法三：将模型文件直接粘贴到LTCYLTspiceIV\ib\cmp中的相应文件中。如要将PSPICE的Diode.lib的模型全导入到cmp中的standard.dio中。先用记事本打开Diode.1ib，全选，复制。而后用记事本打开standard，dio，在其适当的位置粘贴，关闭。发现二极管库里多了很多元件（见下图）。三极管同理。

白光LED（White Light-Fmitting Diode）以其高效、节能、环保、寿命长、无污染等优点逐渐取代传统的白炽灯成为新一代照明光源。与此同时，与LED配套的驱动集成电路的研发也由LED的应用逐渐普及而得到长足的发展。本文对基于LDO（Low dropout voltage 1inear regulator）恒流型的白光LED驱动集成电路进行了设计分析。该驱动电路采用PWM亮度调节模式，支持3位数字信号输入，8段亮度调节功能。在电路设计中，根据要求设计了电路的总体框图，再对电路的所有子模块电路进行了详细设计与分析。电路主要有以下模块组成：电压基准源、振荡器、锯齿波发生器、DAC模块、PWM比较器、LDO。电压基准源为各个子模块提供基准电压。锯齿波发生器将振荡器输出的100KHz时钟信号转换为锯齿波信号，该信号与DAC的输出电压通过PWM比较器比较后得到亮度调整信号。亮度调整信号经过LDO的整形后控制驱动模块的开和关，使电路输出恒定的驱动电流。在中芯国际0.35um工艺库下，使用Hspice仿真软件对电路进行了模拟仿真。模拟结果表明该电路完成了设计功能、达到了预先制定的设计指标。整个电路以恒定的电流输出，输出电流达到了350mA，可以驱动lW的大功率白光LED。满足了电源电压在10%波动时，输出电流的变化量不超过5%。整个控制电路的效率超过了85%。关键词：PWM调制、LDO、恒流驱动
