Combining an internal high voltage power MOSFET and fast- switching gate driver, the device is designed to switch a laptop, tablet and other small form-factor system power supplies in the most efficient way. The wide input voltage range of 0.5V-17V and an output current of 6A make the device ideally suited for a wide range of Low Voltage, High Current System Architecture.

Power Management ICs (PMICs)

Power Management ICs, more commonly known as PMICs, are devices that control the output voltage of a power source, typically in a system with multiple components. With the integration of multiple componentsinto single PMIC chips, a given power supply system can be monitored and regulated in order to ensure optimal performance and working conditions. Moreover, in systems with multiple power sources, PMICs help in identifying the best power source and distributing power accordingly.

Voltage Regulators

Voltage regulators are used in power delivery systems to maintain a stable output voltage, irrespective of variations in the load and input voltage. They are commonly used for electronic circuit power supplies, motor control, batteries and various other applications. Voltage regulators are classified into two basic types; linear regulators and switching regulators. Generally, voltage regulators are popular for their low cost, low power consumption, and simple circuit design,

Special Purpose ICs

Special purpose ICs are ICs which are designed for specific applications and use. They generally contain built-in functionality to perform specific tasks and operations, and are often used where standard ICs may not be suitable. This type of IC is ideal for applications when space is a limiting factor, as they are oftentiny in size yet still provide complex functions.
