LM555 Voltage Doubler - del50007


This circuit shows the voltage doubler working with a 555. LM555 has good drive 200mA, both Vcc and Gnd.

"A 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) applications.

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 makes toys.

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.-  Rob Paisley,

Jochens High Voltage Page

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 Energy Behavior.

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 out ideas.
Threshold Voltage

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.
