220v转5v电动牙刷单片机EN8F2712供电芯片

220v转5v电动牙刷单片机EN8F2712供电芯片,工作电压2.0V 到5.5V


电动牙刷是由干电池、电池盒、微型直流电机、金属护板、主控芯片EN8F2712以及充电装置组成。

电动牙刷单片机EN8F2712供电芯片,它的工作电压2.0V 到5.5V，通常用直流5v供电。电动牙刷基本上都是用交流电220v输入，如何

把交流220v降压成5v，那就要用到我们这颗非隔离降压芯片了，从45v-265v间宽电压输入 ，输出5v时最大 电流可以到700ma，给

电动牙刷单片机EN8F2712供电完全没有问题。

220v to 5v electric toothbrush single chip microcomputer EN8F2712 power supply chip, working voltage 2.0V to 5.5V

The electric toothbrush is composed of dry battery, battery box, micro DC motor, metal shield, main control chip EN8F2711 and charging device.

The electric toothbrush single-chip microcomputer EN8F2712 power supply chip, its working voltage is 2.0V to 5.5V, usually with DC 5V power supply. Electric toothbrushes are basically 220v AC input, how

To step down AC 220v to 5v, then we need to use our non-isolated step-down chip, from 45v-265v wide voltage input, the maximum current can reach 700ma when outputting 5v, give

There is no problem with the power supply of the electric toothbrush single-chip EN8F2711.
