We can do a step-up conversion without using transformer. Using this circuit, a 5V DC source can be converted into 15V. Please note that there is no power gain here, as we cannot create energy from nothing, it means that we can leverage the voltage but the current will drop. This circuit can provide 15V source but the maximum current […]

A normal 9V battery would be considered as dead battery when the voltage falls below 7 Volts. With this switching regulator, a lifetime of a 9V battery will be extended by boosting the voltage if the battery voltage falls under 7.5V. This circuit will maintain the voltage at 7V until the battery voltage falls down to 2.2 volt, a point […]

A switching voltage regulator circuit shown in the schematic diagram here can be a low cost solution for your high efficiency requirement electronic circuit design. Unlike other switching regulator circuit that uses special purpose integrated circuit (IC), this circuit uses a standard linear regulator LM317 IC. LM317 regulator IC provide a stable internal voltage reference, and provide the adjustment method. […]
