Simple Step up DC TO DC Converter by LM555
If you will take an interest to try build DC TO DC Converter step up Volt model base. I thinks , when you have evered to play IC LM555 that highly popular come to already. As a result is try lead it comes to use in this work sees ? From its circuit has can to transform 12V from is 18V by give current get tall about 3A. By P1 and P2 fine decorate the frequency are appropriate for make the circuit transforms well for the clearness of this circuit. I advises read to wasp in original website http://www.xs4all.nl/~jwasys/old/diy4.html#stepup better sir.

Somsak is person see the website of me take an interest try build Variable Regulater Switching LAB Supply. By fine decorate voltage output get 0-50V and fine current get 5A. I then choose this circuit , which use IC TL494 be pillar equipment (Switchmode Pulse Width Modulation Control Circuit). And use pretty litter transistor number MJ15004 then give current get enough tall. But should choose pot size modifies about 5A go up with. When see the circuit has already may inappropriate with a novice. Because use many equipments then the gift uses the tie perhaps specially with , be lucky sir.

In case of you want DC Voltage adapter circuit 1.4V sizes and use current about 100mA. I begs for to advise this circuit. Be the one choice because it easily but good effective sir. Use base equipment only mourn not ? only By voltage fall straddle diode 2 the . Be valuable about 1.4V take Voltage here go to be usable which be valuable be stable moderately sir.
