DC to DC converters play a vital role in modern electrical systems, widely used in various kinds of applications. CXA10-48S12 is a type of DC-DC converter operating in the intermediate-output range. It is capable of providing adjustable, low noise and efficient power over a wide range of input voltages. This application note aims to provide an overview of the CXA10-48S12\'s application field and its working principle.

Application Field

CXA10-48S12 is mainly used in laptops and industrial equipment. The distinguishing feature of the CXA10-48S12 converter is that it can provide adjustable, low-noise, and power efficiency over a wide range of input voltages. The other features are step down and step-up capability and wide input voltage range of 6.5-26V with an adjustable output voltage of 0.6 - 48V. It is capable of outputting up to 24A of current, with an efficiency of up to 92%. Furthermore, it is protected against over-current, over-voltage, and over-temperature conditions. Additionally, CXA10-48S12 can also be integrated with other components, like a buck boost regulator, to provide even more performance.

Working Principle

CXA10-48S12 works on the principle of inductive step-down and step-up regulation. Initially, the current from the power supply is fed to the transformer, which converts the alternating current(AC) into direct current (DC). This process of conversion can be divided into two main stages: rectification and regulation.

It uses a switching technique for rectification, where the DC voltage is filtered into a constant DC voltage. This is done by switching off and on at very high speeds between the zero and peaks states to form a smooth average current. The switch on/off ratio forms the key factor in controlling the output voltage, with frequency control oscillators (FCOs) regulating the ratio.

Following rectification, there is a two-level regulation stage, where the output voltage is smoothened and stabilized. The first level comprises of an inductor and capacitor filter, which helps to smooth the output of the transformer and remove the ripple. The second level of regulation includes an onboard control circuit with variable operating frequency to monitor the output voltage and adjust the current levels.

An additional component, the buck-boost regulator, can be used to further enhance the CXA10-48S12’s capabilities. The regulator helps to convert an input voltage above or below the optimum range into an acceptable voltage level for the CXA10-48S12. This is done by using pulse width modulation (PWM) to adjust the gain of the input voltage to the desired output.

Conclusion

CXA10-48S12 is a DC-DC converter ideal for laptops and industrial equipment. It is capable of providing adjustable, low noise and efficient power over a wide range of input voltages with step down and step-up capability and wide input voltage range. The working principle of CXA10-48S12 includes rectification using switching technique and a two-level regulation stage to ensure a smooth and constant output current. Additionally, a buck-boost regulator can be added to the circuit to improve the converter’s capabilities.
