DC DC Converters circuits design electronic projects with explanation

5 to 12v converter using ADP1612

Using the ADP1612 step-up dc to dc converter manufactured by Analog Devicescan be designed a very simple step up converter.
This step-up converter electronic project will provide a fixed 12v dc output voltage from an input voltage between 2.7 to 5 volts. ADP1612 is a switching converter with an integrated power switch capable of providing an output voltage as high as 20 V.
