5 to 12V DC converter circuit using LTC3872
Using LTC3872 integrated DC DC controller, manufactured by Linear Technology, can be designed a high power 5 to 12 volt converter circuit.
The No RSENSE architecture eliminates the need for a sense resistor, improves efficiency and saves board space.
The 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 DC converter electronic project require a 5 volt DC input and will provide a 12 volts output at a maximum output current of 2 ampere .
