Designing a Boost-Switching Regulator with the MCP1650
Today’s electronic circuits require a number of different voltage potentials. Powering silicon devices like microcontrollers or digital logic require a different voltage than bias supplies or powering strings of LEDs. A system can very easily contain a combination of circuits that require different voltages. With only a single input voltage delivered to the system, a power regulator is needed to produce the necessary voltages.
This application note focuses on inductor-based, switchmode power converters, more specifically, the boost regulator topology. The boost topology produces a regulated output voltage that is higher than the unregulated input voltage source. An example of a boost regulator design is explored using Microchip’s MCP1650 boost controller.
