AC DC Converters - JWT75522/RB Application Field and Working Principle

AC/DC converters are devices utilized to convert alternating current (AC), produced by a source such as the power grid, into direct current (DC) suitable for the powering of electronic devices. The JWT75522/RB is one type of AC/DC converter that is commonly used for providing power to small DC motors, such as those found in consumer electronics. This article will discuss the application field of the JWT75522/RB and its working principle.

Application Field of JWT75522/RB

The JWT75522/RB has a wide range of applications in DC motor speed control, switching power supplies, LED lighting, and other consumer electronic devices. The device is capable of providing regulated DC voltage ranging from 18 to 32V, making it an ideal choice for both industrial and consumer electronics. As it is a non-isolated converter, it also has the ability to reduce the effects of noise and interference from outside sources. Additionally, the device features over voltage, short-circuit, and thermal protection, making it a safe choice for use.

Working Principle of JWT75522/RB

The JWT75522/RB features a step-down topology, allowing it to convert a DC voltage ranging from 18 to 32V into a regulated DC voltage, usually ranging from 0 to 24V. The device works by using two power MOSFETs in a synchronous rectifier configuration to efficiently convert the input voltage into a regulated output voltage.The JWT75522/RB also utilizes a maximum-duty-cycle limit to achieve steady and stable operation during switching. This limit is essential for the proper operation of the device since it prevents the input voltage from exceeding the output voltage. Additionally, the device also employs over-current protection, which cuts off current when it exceeds a certain value, thus ensuring the safety of the user.

Conclusion

The JWT75522/RB is an ideal choice for providing power to small DC motors and other electronics due to its wide range of applications and capabilities. The device features a synchronous rectifier configuration, providing efficient conversion of the input voltage into a regulated output voltage. Additionally, the device has a maximum-duty-cycle limit to ensure steady and stable operation as well as over-current protection for safety. Therefore, if you are in the market for an AC/DC converter, the JWT75522/RB is an ideal choice.
