CBS504815-RF2

DC DC converters play an increasingly vital role in our daily life. As technology evolves, more and more DC DC converters come into existence. CBS504815-RF2 is one of the types of DC DC converters. It has a wide range of application in applications ranging from communications, automotive, aerospace and medical area.

CBS504815-RF2 is a two-stage DC/DC converter which combines the advantages of a buck converter and an active clamp circuit and uses the Snubberless switching structure, providing a solution with high efficiency and low EMI output. This unique two-stage converter features a non-synchronous buck topology, allowing the efficiency of the converter to reach up to 96%.

The working principle of CBS504815-RF2 can be summarized using the following diagrams. To understand the fundamental concept of this converter, let us look at the buck-clamping converter in the figure below. The buck converter depicted on the left has two inductors and two switches, which allow the current to flow in one direction only. The active clamp circuit on the right includes one additional switch and two discharge diodes which are used to clamp the output voltage.

When the input voltage is applied, the lower switch of the buck converter turns on, which allows the current to flow in the lower inductor through the diode and increases the output voltage. The lower switch then turns off and the upper switch turns on, allowing the current to continue flowing in the upper inductor. The voltage on the output then decreases.

At the same time, the clamp circuit is activated. The upper switch is switched on, which causes a discharge current to flow through the diode D2 and the load. The voltage on the output is thus clamped, preventing it from increasing beyond a certain value.

At the end of the cycle, both switches are turned off and the output voltage starts to fall. The clamp circuit now starts again and the voltage is clamped to the initial value. This cycle is repeated, as long as the input voltage and load current remain constant.

The CBS504815-RF2 converter has been designed with high efficiency, low EMI and low total harmonic distortion in mind. It has been rigorously tested in a broad range of operating conditions and is suitable for a wide range of applications, including automotive, aerospace and medical. With its small and lightweight package, it is ideal for applications that have a number of power requirements.

To conclude, the CBS504815-RF2 has been developed to meet the highest performance requirements. Its robust design, wide range of application, and low EMI provide a reliable solution for a variety of applications. Its Snubberless switching structure also allows for higher efficiency and a longer service life, making it an ideal choice for many types of applications.
