The boost step-up regulator based an LM2577-ADJ switch voltage regulator chip.
This high power led flashlight circuit look like torch by 1.5V battery only so it can be used, small so Easy to carry in various places,also very bright [...]
The car dc to dc converter project for converts from 12V car battery to dual voltage of +40V Ground and -40V Available of +/-27V ; +/-30V ; +/-30V; +/-50V
This is 5V to 12V boost converter circuit or higher using transistor circuit,When if you want a negative voltage from a positive power supply.
Let's build a small solar AA battery charger. In an era of expensive energy better. In an era that energy is more expensive every day. Alternative energy is a good…
I would suggest the IC-555 DC boost converter circuits is a key equipment that it is popular and easy to uses so can be used in many circuits.
This 12v to 300v dc-dc converter circuit. By 2N3055 transistors and 2N1305 are pillar equipment and power transformer transform the sky tallly go up then change voltage regulator rectifier with…
