How is the boost in the power IC achieved? Clear and concise

    1. * * Charging stage * *: In this stage, the input voltage is applied to the inductive component, and the switching transistor (usually MOSFET) is in a conductive state. In this case, the inductive component stores energy and the inductive current gradually increases.     1. * * Charging stage * *: In this stage, the input voltage is applied to the inductive component, and the switching transistor (usually MOSFET) is in a conductive state. In this case, the inductive component stores energy and the inductive current gradually increases. 2. * * Discharge stage * *: When the switching tube is closed, the energy storage in the inductive component begins to be released. Due to the characteristics of inductive components, the current cannot change suddenly, so the current of inductive components flows towards the load, resulting in an increase in output voltage. The stability of the output voltage can be achieved by controlling the opening and closing time of the switching tube.

    The Boost converter achieves stable output voltage regulation by periodically adjusting the opening and closing times of the switching tubes. In addition, controlling the size of inductive components, switching frequency, and design of feedback loops are also important factors that affect boost efficiency and stability.
