Some problems in the electronics job, can modify or bring devices come to apply available not difficult If we know the principles and limitations of those devices. As the project is being offered at this time, will be bringing sized batteries 1.5 volt connected through an electronic circuit called dc converter to increase the voltage to have higher value be 9 volt instead of the battery 6 pack, connected series.
It can also increase the voltage from the battery 3 volt to 9 volt as well be the original circuit, and it will allow more current.
Properties of the IC TL496
- A TL496 be control circuit of the power supply, by the circuit was designed, so that the output voltage is 9 volt. For the change of the input voltage, which comes from the battery 1 or 2 pack. The TL496 operates in a switching regulator, the power loss is less than the typical linear regulator.
