DC BOOST CONVERTER 3.3-5V TO 12V, 100mA.

A boost converter (step-up converter) is a DC-to DC power converter with an output voltage greater than its input voltage. DC to DC converters are important in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily.
