Intel_苹果_A1286_k18(HM57)时序分析
学习有效期 999天 （随到随学）
简介
本课程由迅维金牌讲师——月饼老师讲解，主要介绍了Intel_苹果_A1286_k18(HM57)时序分析。
本时序由月饼老师原创，从插入适配器产生PPDCIN_G3H，经过Q7080的体二极管产生PPDCIN_G3H_OR_PBUS；电池模式下，由电池经过Q7055体二极管，再经过充电电路的上管Q7030的体二极管给PPDCIN_G3H_OR_PBUS供电，PPDCIN_G3H_OR_PBUS给U6990的VIN供电，并直接加到EN，芯片输出PP3V42_G3H。这是一个降压型开关稳压器，内部集成了升压和钳位二极管。PP3V42_G3H给VR5020供电，VR5020输出PP3V3_S5_AVREF_SMC。PP3V42_G3H给EC的AVCC供电，PP3V3_S5_AVREF_SMC给EC的AVREF供电，EC得到待机供电后，给Y5010供电，产生20M时钟给EC。了解更多详细内容，可观看本课程视频教程！
