# Symmetrical DC to DC Converter With IC555

**Symmetrical DC to DC converter with IC555** serves to convert the DC voltage one pole (single) come to be in proportion DC voltage (+/- Gnd). To transform a solitary DC voltage into DC voltage in proportion, DC to DC voltage converter making use of IC NE555. DC to DC converter circuit calls for a +12 volt DC voltage resource to be converted right into DC voltage symmetrical + 5 volts as well as – 5 volts. To create a symmetrical DC to DC converter with NE555 can be seen schematic illustrations and also parts listings DC to DC converter circuit in proportion IC 555 as complies with.

## Schematic Circuit Of Symmetrical DC to DC Converter With IC555

The symmetrical DC to DC converter with IC555 above constructed utilizing astable multivibrator NE555 with functioning regularity of 160 KHz. Operating frequency astable multivibrator NE555 circuit in figure above determined by the resistance worth R1, R2 and capacitance C8.

### The working principle Of Symmetrical DC to DC Converter With IC555

The functioning concept symmetric DC to DC converter with IC555 as adheres to. 160 KHz pulse result of the astable multivibrator NE555 circuit then corrected symmetrically making use of 4 diodes BAT85. The output of this rectifier circuit produce a DC voltage that is then regulated by a symmetrical positive voltage regulator LM7805 and also LM7905 poor voltage regulatory authority so regarding produce an in proportion result voltage of +5 volts DC and also -5 volts to ground.

Symmetrical DC to DC converter with NE555 has an in proportion output +5 volts as well as -5 volts with a current supply capability of 50 mA for every outcome path. The maximum present bring capacity is restricted by the maximum result existing IC NE555 as well as present capacity maximum voltage of LM78Lxx regulator at the result of the symmetrical DC to DC converter with IC555.
