Power Management Integrated Circuit (PMIC)

Power Management Integrated Circuits (PMICs) are a type of integrated circuit that is responsible for controlling and regulating the power management in a wide variety of electronic systems. They can be used in a variety of applications such as charger, power converter, and even vehicle control systems. PMICs allow for efficient power management by providing a stable supply voltage and current to the system. They can also help to minimize power loss and ensure the system remains safe and reliable. PMICs are actively used in the most modern electronic systems and they provide an important function for many systems.

AC DC Converters

AC DC Converters are devices which are responsible for converting alternating current (AC) of a certain frequency and amplitude into direct current (DC) of a certain voltage and current. AC DC Converters are used in a wide variety of applications including home electronics, cars, computers, and aerospace applications. AC DC Converters typically require external components such as transformers and inductors to provide the necessary isolation and transformation functions. They are used to regulate the flow of current to ensure the desired output voltage and current are achieved.

Offline Switchers

Offline Switchers are devices that are used to switch between two or more alternative power sources in the absence of input power. They are typically used to switch between AC mains and backup battery power in case of a power outage. Offline Switchers are designed to provide a quick and reliable transition between the sources to minimize downtime and ensure that the system is provided with a constant and stable source of power. Offline Switchers typically feature a built-in automatic switch over in the event of a power failure.
