LM555 Voltage Doubler - del50007
This circuit shows the voltage doubler working
with a 555. LM555 has good drive 200mA, both Vcc
voltage multiplier is an electrical circuit
that converts AC electrical power from a lower
voltage to a higher DC voltage by means of
capacitors and diodes combined into a network.
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
The explanations for the circuits on these pages
cannot hope to cover every situation on every
layout. For this reason be prepared to do some
experimenting to get the results you want.-
Jochen Kronjaeger shares his knowledge about HV or
High Voltage. Youngsters should not experiment with
high voltage or even mains voltage. Use batteries.
This resource on HV helps you learn about High
HV and Mains voltage, anything above 50V - 1A -
100Hz is capable of causing injury and damage to
human body. Students and Learners, please be
accompanied by a HV professional when you are trying
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.
