2301_76767447: ren另一端接地吗 1.2V转3V芯片,电路图很少就三个元件szpc1621: The PC8609 is a synchronous step-up converter with 0.65μA ultra low quiescent current. It is designed for products powered by alkaline battery, NiMH rechargeable battery, Li-Mn battery or rechargeable Li-Ion battery, for which high efficiency under light load condition is critical to achieve long battery life operation. The PC8609 step-up converter only consumes 0.65μA quiescent current under light load condition and can achieve up to 75% efficiency at 10μA load with fixed output voltage version. It can also support up to 300mA output current from 3.3V to 5V conversion, and achieve up to 93% efficiency at 200mA load. The PC8609 also offers both down mode andpass-through operation for different applications.In down mode, the output voltage can still be regulated at target value even when input voltage is higher than output voltage. In pass-through mode, the output voltage follows input voltage. The PC8609 exits down mode and enters into pass-through mode when VIN > VOUT + 0.3V. 13603089 80V转5V,恒压可调恒流电源PCB设计建议规范PW2153LC羊·A: 反馈1的vout原理图中接什么? 5V降压1.8V芯片,稳压电路设计建议PW2059qq_52434746: 讲的很明白,请问这是官方说明吗,官网上哪里能找到? 24V转5V降压芯片PW2205,PCB布局图册咖妃不配糖: R3是0R电阻嘛? |
