Power supply working current of domestic single chip EN8P2712 hair straightener:
< 170 uA at 3V, 8MHz
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.
