PMIC - AC DC Converters, Offline Switchers

Power Management Integrated Circuits (PMIC), also known as a power system on chip (PSOC), is the integrated circuit that controls the power management of a system. The STR-W6735N is a particular PMIC that focuses on AC/DC conversion, offline switchers, and surge protection. In this article, we will delve deeper into the application field and working principle of the STR-W6735N.

Application Field of STR-W6735N

The main application of the STR-W6735N is AC/DC conversion. This is done by regulating the input voltage of the PMIC, usually 85-265V, to a lower, regulated DC voltage such as 5V or 12V. This regulated DC voltage is then used to power the system’s components and peripherals. Thanks to its built-in secondary protection features, it is suitable for use in a wide range of applications, such as consumer electronics and other industrial applications.

The STR-W6735N can also be used as an offline switcher. This means that it is used to switch the power supply of a device between AC/DC and DC/DC when the power supply fails. This makes the STR-W6735N a highly reliable and efficient power management integrated circuit, suitable for use in industrial as well as consumer applications. Furthermore, the built-in surge protection of the STR-W6735N makes it suitable for use in medical devices.

Working Principle of STR-W6735N

The STR-W6735N is a synchronous rectification AC/DC converter with a peak current-mode topology. It is based on primary side regulation, so it does not require an optocoupler for proper regulation. This means that it is more efficient and reliable than traditional AC/DC converters that use an optocoupler for regulation.

At the heart of the STR-W6735N is a controller that regulates the input voltage to a predetermined, output voltage. The controller is made up of several components, including a power transistor that is used to switch the input voltage and an error amplifier that compares the output voltage to the reference voltage and then adjusts the power transistor accordingly.

In addition to the components mentioned above, the STR-W6735N also has a built-in secondary protection feature. This feature can prevent damage to the system due to over-current, over-temperature, or other faulty conditions. All of these features make the STR-W6735N an excellent power management integrated circuit.

Conclusion

The STR-W6735N is a power management integrated circuit that is suitable for AC/DC conversion, offline switchover, and surge protection. It is based on primary side regulation, so it does not require an optocoupler for proper regulation. Furthermore, it has a built-in secondary protection feature that can protect the system from over-current, over-temperature, and other faulty conditions. All of these features make the STR-W6735N a reliable and efficient solution for power management.
