LM555 Voltage Doubler - del50007
This circuit shows the voltage doubler working
with a 555. LM555 has good drive 200mA, both Vcc
Using LEDs with Battery Power - Here you can
learn about LED and how to use them.
This is a simple voltage doubler using a 555,
this can help boosting a low battery voltage to
power a logic or opamp circuit.
Voltage Doublers and Multipliers - Diodes
and Caps can boost voltage for low power(current)
Voltage multipliers can be used to generate bias
voltages of a few volts or tens of volts or
millions of volts for purposes such as high-energy
physics experiments and lightning safety
testing." I drew this for a person who
On trigger at pin 2, Output goes high,
timing cap charges from 0 to 2/3 Vcc the pin 6
of an internal comparator senses it & trips.
Pin 7 goes low discharging the cap. Pin 3 goes
low too. This ends the Timing Cycle.
Time Delay Power off
This circuit uses the two internal 1/3 and 2/3
comparators to create a Time delay switch.
