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

Time:2024-03-20 Views:232
    Boosting in power integrated circuits (ICs) is typically achieved through the use of switch mode power converters. Among them, the most common is the boost type DC-DC converter, also known as the boost converter or boost converter. The basic principle of a Boost converter is to achieve voltage increase by periodically switching an inductor. Its work cycle includes two main stages: charging stage and discharging stage.
    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.

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.
    Overall, Boost converters are an effective way to achieve boost, and they are widely used in many applications, such as portable electronic devices and automotive electronic systems.
