应用信息 输入电容器 VIN 和GND 引脚之间需要10μF 的输入电容。电容器应尽可能靠近VIN 引脚，建议使用电解电容器。必须考虑公差和温度系数，以确保电容器在整个温度和工作条件范围内工作。 输出电容器
在实际应用中，选择输出电容器以保证其稳定运行是非常重要的。稳定和正确操作的最小电容为1μF。电容公差应在工作温度范围内±30%或更好。建议电容器类型为MLCC。 空载稳定性 PW6206将在无外部负载的情况下保持稳定和调节。这在CMOS RAM保持活动应用中尤其重要。 典型电路 下图显示了PW6206设备的典型应用电路。根据应用情况，应仔细选择外部组件的值。在插拔应用中，由于芯片上电源的插入和拔出引起的过冲会损坏芯片，因此建议VIN小于30V，输入电压峰值不超过45V。 在封堵应用中，建议R、Cin选用如下： 1Cin=10UF~100UF电解电容器，最大电压大于50V，R=0； 2Cin=1UF~10UF MLCC，最大电压V大于50V，R=2Ω，1206型电阻器应仔细选择，以确保有足够的裕度来承受插入期间的浪涌电流。

WD6122 红外遥控发射电路 六. 功能说明 1. 编码方式 WD6122 所发射的一帧码含有一个引导码，16位的用户编码和8位的键数据码、键数据码的反码也同时被传送。码型结构如下： 引导码由一个9ms的载波波形和4.5ms的关断时间构成，它作为随后发射的码的引导，这样当接收系统是由微处理器构成的时候，能更有效地处理码的接收与检测及其它各项控制之间的时序关系。编码采用脉冲位置调制方式（PPM）。利用脉冲之间的时间间隔来区分“0”和“1”。每次8位的码被传送之后，它们的反码也被传送，减少了系统的误码率。 2．键盘输入矩阵 WD6122键盘输入矩阵请参考下图： 3．按键输入 WD6122 在键扫描输入端KI0~KI7 和键扫描定时信号输入/输出端KI/O0~KI/O7构成的8×8 矩阵上共设置64 个按键。 只有第21#键与其它连在KI/O5 线上的键即22# 、23# 、24#键组合才能实现双重按键功能。即只有下列按键的组合才能进行双重按键操作。 1) 21#键与22#键；2 ）21#键与23#键；3 ）21#键与24#键 每个键输入端与电源负端VSS之间均接有下拉电阻。当有超过一个以上的按键（除非双重按键的组合21#与22#键21#与23#键21#与24#键）同时按下时，码的发射输出将停止。 当一个键按下时先读取用户码和键数据码，22ms后遥控输出端（REM）启动输出，按键时间只有超过22ms才能输出一帧码，超过108ms后才能输出第二帧码。 Edited by Foxit Reader Copyright(C) by Foxit Corporation,2005-2010For Evaluation Only.
