LTC3872 5 to 12 volt converter electronic circuit project

A very simple high efficiency and high power 5 to 12 volt converter electronic circuit project can be designed using the LTC3872 constant frequency current mode boost DC DC controller that drives an N-channel power MOSFET and requires very few external components.
The No RSENSE architecture eliminates the need for a sense resistor, improves efficiency and saves board space.

The LTC3872 provides excellent AC and DC load and line regulation with 1.5% output voltage accuracy. This circuit incorporates an undervoltage lockout feature that shuts down the device when the input voltage falls below 2.3V.
High switching frequency of 550kHz allows the use of a small inductor . This converter electronic circuit require a 5 volt DC input and will provide a 12 volts output at a maximum output current of 2 ampere .
