220v转3v供电芯片

 国产单片机EN8P2712直发器供电工作电流:

  在3V、8MHz 时< 170 uA

 待机电流:

  V 时典型值为<1UA

  看门狗定时器电流:

  当电压在2.0V 时,典型值为300nA

  TIMER1 振荡器电流:

  当频率为32khz,电压为2.0v 时,典型值为4uA 全静态设计

  宽工作电压范围:1.8V 到6.0V

如何

把交流220v降压成3v,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3v时最大 电流可以到700ma,给


直发器单片机EN8F2712供电完全没有问题。

 

Power supply working current of domestic single chip EN8P2712 hair straightener:
 
  < 170 uA at 3V, 8MHz
 
 stand-by current:
 
  V, the typical value is <1UA
 
  Watchdog timer current:
 
   When the voltage is 2.0V, the typical value is 300nA
 
  TIMER1 oscillator current:
 
   When the frequency is 32khz and the voltage is 2.0v, the typical value is 4uA. Fully static design
 
  Wide working voltage range: 1.8V to 6.0V

how is it
 
To step down AC 220v to 3v, then we need to use our non-isolated step-down chip, from 45v-265v wide voltage input, the maximum current can reach 700ma when the output is 3v.
 
There is no problem with the power supply of the single-chip microcomputer EN8F2712 of the straightener.
