Power Supply Circuits

This simple USB to 12V DC boost converter circuit works as a DC-DC step-up converter. It takes power from a USB port that gives 5V DC and increases it to 12V DC. This circuit is really useful for powering small 12V devices using a regular USB source, like a power bank or a computers USB […]

A simple circuit using the IC LM2678 makes a 5V DC-DC buck converter, which is a type of DC-DC converter that lowers a higher voltage to a lower one with a switching regulator. The IC LM2678 is known for being very efficient as a step-down (buck) switching regulator and can deliver an output current of […]

A simple step-up voltage regulator circuit using the IC LM2700 chip is really important when you need to increase a low direct current DC voltage to a higher level. This is especially useful for battery powered devices where keeping a steady output voltage is crucial even if the input supply changes. The LM2700 acts as […]

A boost converter is a special kind of power converter that changes a lower DC voltage into a higher one. This is really helpful for battery powered devices because sometimes the battery voltage is lower than what the device needs. This Simple 5V Step-Up Converter Circuit uses the LTC3440 chip to change an input voltage […]

A Boost Converter circuit is made to raise the voltage from 12V to 120V DC, which is super important for adjusting voltage levels when we need to. This circuit takes a 12V DC input and transforms it into a powerful 120V DC output making it really handy for times when we need a high voltage […]

The Step-Up Converter Circuit: 6V to 15V Boost Regulator is made to turn a 6V DC input into a powerful 15V DC output using the smart IC LM2585 switch mode regulator chip. The IC LM2585 is a fantastic chip designed for boosting voltage. You can use it in lots of different ways, like in flyback […]
