Working Principle

The MCP19119-E/MQ series of voltage regulators are based on a buck-boost converter topology. This topology features an input power stage and an output power stage, whose outputs are regulated by the built-in control logic. The input power stage accepts the input voltage and delivers it to the switching elements, which can alternatively be a MOSFET or IGBT. These switching elements are controlled by the output power stage, which regulates the output voltage and current based on the user-defined parameters.

The output power stage is connected to the switching elements and is responsible for generating the appropriate switching signals to regulate the voltage and current supplied to the load. The output power stage can be configured using the pre-programmed settings that are defined by the user. Additionally, these switching controllers have a variety of built-in protection features, such as over-voltage and over-current protection, that can prevent damage to the application.

In summary, the MCP19119-E/MQ series of voltage regulators is an excellent choice for a variety of applications.
