Using this circuit we can convert 5V DC from the computer USB port to 12V DC and a circuit like this will find a lot of application in USB powered systems. The heart of this circuit is IC LT1618 which ...

This is a 5V to 12V DC-DC step-up (boost) converter circuitry that is especially ideal for the USB powered applications. First of all a USB port has two current supply modes. Before detecting the ...

Linear Tech has brought out two synchronous current mode buck boost converters that deliver up to 600mA of continuous output current from a wide variety of input sources, including single- or multiple ...
