AC/DC converters and offline switchers provide steady and reliable power sources for a wide range of electronics applications. The LNK353G is a high-efficiency, low-power AC/DC converter from Power Integrations that combines the advantages of both offline switchers and AC/DC converters. The device provides the flexibility needed for applications requiring high power factor, high efficiency, and low power loss. The LNK353G also combines integrated protection features such as over-current and over-temperature protection, making it well-suited for many power supply solutions.

The LNK353G features a high-efficiency synchronous rectified buck converter with low standby power loss and low-EMI operation. The device utilizes an internal feedback loop to regulate the output voltage, allowing it to always maintain constant output voltage even when under heavy load. The converter also ensures that the output voltage remains within safe limits during start-up and shut-down conditions. The converter is designed to provide a high-power factor solution while meeting international harmonic requirements.

The LNK353G also features low-EMI operation with integrated EMC and ESD protection to ensure that noise generated by the unit does not affect other equipment. The device also includes protection against input under and over voltage, over temperature, and over current. The combination of the low-EMI performance and the integrated protection features make the LNK353G a robust and reliable solution for any power supply application.

The LNK353G operates from an input voltage range of 80 to 264V AC. It has a fixed switching frequency of 73kHz and a wide range of output voltages from 5V to 24V. It provides up to 20W of power and is 1/4th of the size of competing solutions. The LNK353G also provides an adjustable soft-start time so users can customize the start-up parameters of their device.

The combination of high efficiency, low standby power loss, low-EMI operation, and integrated protection features, make the LNK353G a reliable and cost-effective solution for any power supply application. The device can be used in a wide range of applications such as motor drives, lighting, industrial control, automotive, and server applications. The device offers a compact, cost-effective solution for any power supply design.
