新人，研究一下快充，pd3.0的PPS具体是怎么实现的呀，怎么发送的有，人能提供规范么。谢谢

2020年是超级快充成为主流的一年。移动通信终端的应用越来越广泛，使用频度越来越高，总体电能消耗量不断增大，消费者需要频繁充电。一些知名厂商相继推出40w，66W甚至120W快充技术，让旗下的电子设备充电速度进一步缩短。那么，现在的智能终端市场，快充技术的现状如何？在单位体积电池容量技术很难突破的前提下，快充技术如何能够满足消费者对于短时间充电的要求呢？本次将为大家详细介绍快充系列测试解决方案。 pc与移动端同步直播，链接：http://live.vhall.com/746105625 直播大纲：1.快充的意义及原理解析2.快充充电协议测试中的难点解析：如何验证适配器在不同的协议诱变下，能否发生正确的电压换挡，提供对应的输出功率。3.如何快速搭建快充充电器电气性能测试框架，简化测试线路。4.借助电池模拟器深度解读“充电5分钟，通话两小时”背后电池充电速度的重要性。u  快充充电协议的测试 1）快充专用负载相当于将诱变器内置于设备中，简化线路连接复杂度 2）标配快充测试板，工程师可直插Micro USB及Type-C的USB充电线缆 3）内置八种快充通信协议，QC2.0/QC3.0/PE+/PE2.0+/USB PD2.0/USB PD3.0/FCP/SCP，满足不同厂商快充的测试需求 4）提供自动测试模式，可实现对快充适配器恒压恒流不同充电阶段的性能验证 预约参与互动抽奖环节，还有好礼相赠~前十名预约成功并参会的观众，将获赠“宇航员小夜灯”一份直播过程中，进行三次随机抽奖，多重礼品等你来哦。

PW6566 系列是使用 CMOS 技术开发的低压差，高精度 输出电压，低消耗电流正电压型电压稳 压器。由于内置有低通态电阻晶体管，因而压差低，能够获得较大的输出电流。为了使负载电流不超过输出晶体管的电流容量，内置了过载电流保护电路、短路保护电路。 PW6566 系列采用 SOT-23-3L 小型封装。 PW6566输出（3.3V，3V，2.8V，2.5V，1.8V） 代理商：深圳市夸克微科技 phone ：13528458039 QQ 13528458039 输出：3V 65ZX 65Z565ZQ,65ZW,65ZE,65ZR,65ZT,65ZY,65ZU,65ZI,65ZO,65ZP,65ZA,65ZS,65ZD,65ZF,65ZG,65ZH,65ZJ,65ZK,65ZL,65ZZ,65ZX,65ZC,65ZV,65ZB,65ZN,65ZM,65Z1,65Z2,65Z3,65Z4,65Z6,65Z7,65Z8,65Z9 输出：3.3V 662K 662V 662L662Q,662W,662E,662R,662T,662Y,662U,662I,662O,662P,662A,662S,662D,662F,662G,662H,662J,662K,662L,662Z,662X,662C,662V,662B,662N,662M,6621,6622,6623,6624,6626,6627,6628,6629 输出：2.8V 65X6 65XS 65XL65XQ,65XW,65XE,65XR,65XT,65XY,65XU,65XI,65XO,65XP,65XA,65XS,65XD,65XF,65XG,65XH,65XJ,65XK,65XL,65XZ,65XX,65XC,65XV,65XB,65XN,65XM,65X1,65X2,65X3,65X4,65X6,65X7,65X8,65X9 输出：2.5V 65TL 65T5 65T8 65T9 65T0 65TU 65TP65TQ,65TW,65TE,65TR,65TT,65TY,65TU,65TI,65TO,65TP,65TA,65TS,65TD,65TF,65TG,65TH,65TJ,65TK,65TL,65TZ,65TX,65TC,65TV,65TB,65TN,65TM,65T1,65T2,65T3,65T4,65T6,65T7,65T8,65T9 输出：1.8V  65K5 65KL 65KR 65KH , 65K765KQ,65KW,65KE,65KR,65KT,65KY,65KU,65KI,65KO,65KP,65KA,65KS,65KD,65KF,65KG,65KH,65KJ,65KK,65KL,65KZ,65KX,65KC,65KV,65KB,65KN,65KM,65K1,65K2,65K3,65K4,65K6,65K7,65K8,65K9
