DC to DC converters are commonplace in the electronics industry, providing power conversion between low voltage and high voltage digital and analog circuits. The CES48120-6-N is one such device, a single channel step-up DC/DC converter which is capable of providing a 3.3V output at a maximum load current of 28A. The device has some unique features which make it ideal for certain applications, allowing it to deliver high efficiency and performance. In this article we discuss the application field of the CES48120-6-N and cover its working principle.

The Application Field of the CES48120-6-N

The CES48120-6-N is an ideal choice for applications where an efficient, compact, single channel buck-boost design is required. It has an extremely wide input voltage range, from 6V to 60V, which makes it suitable for applications with varying input voltages, such as portable devices, cars, and industrial control systems. Furthermore, its high efficiency design, at up to 95%, is perfect for applications with limited power budgets. The unique features of the device allow it to provide fast transient responses, as well as low noise operation. The device is also specifically designed for automatic switching between buck and boost modes, which makes it perfect for applications which require load independent regulation.

The Working Principle of the CES48120-6-N

The working principle of the CES48120-6-N is based on the principle of voltage scaling. It utilizes two transistors; the first behaves as a regulated current limiter, limiting the input current to the device, while the second behaves as an adjustable voltage regulator, controlling the output voltage. The device is designed with an analog feedback loop, which allows it to accurately adjust the output voltage in both buck and boost modes. The device switches automatically between buck and boost modes in order to maintain regulation. Additionally, the device is equipped with a number of protections to ensure safe operation, such as overvoltage, overload and over temperature protections.

The device utilizes a non-synchronous buck-boost topology, in which the transistor acts as a switch to connect or disconnect the inductor to the input/output voltage. The circuit also contains a compensation network, which is used to adjust the slope of the voltage at the output of the device. This allows the device to maintain high efficiency and regulation over a wide range of loads. Additionally, the device\'s low ripple operation ensures that noise is minimized.

Conclusion

The CES48120-6-N is an efficient and compact DC/DC step-up converter, with a wide input voltage range, high efficiency, fast transient response, and low noise operation. It is an ideal choice for applications where an efficient buck-boost design is required, such as portable devices, cars, and industrial control systems. The device utilizes a non-synchronous buck-boost topology, with an analog feedback control loop to precisely regulate the output voltage. Additionally, the device is equipped with protections to ensure safe operation.
