Boost Converter Circuit 555

In this boost converter circuit timer ic 555 configured in astable multivibrator mode and we can adjust the output.

Boost converter circuit 555. Dc dc boost converter using 555 timer. In this circuit the feedback is created by using a transistor to pull down on the control voltage node of the 555 which reduces the upper switching threshold. I ve made a boost converter circuit with a mosfet as a switch and a 7 555 timer operating as an astable oscillator and it s output goes directly to the mosfets gate pin. The above circuit can act both as a buck converter or a boost converter will depend on how the 555 pwm output is adjusted also the inductor will need to be dimensioned as per the load current amps for optimal functioning.

The filaments typically have forward voltage in order of 70v and there are not many suitable power supplies available in that voltage range. The problem is that the input voltage for the boost converter is unstable solar panels.

If you need high voltage from 3 volt battery you can use this circuit to boost supply voltage. The power through a boost mode converter is regulated by varying the duty cycle of the switching element.
