DC-DC converters are a practical and efficient way to regulate electrical power. They are found in a variety of industries including automotive, aerospace, telecommunications, and industrial applications. The XCL202B191ER-G is a typical DC-DC converter. This article will discuss the application field and working principle of the XCL202B191ER-G.

Application Field

The XCL202B191ER-G is a multi-output DC-DC converter, specifically a dual output, 6-32V input voltage. Its purpose is to provide a dependable power source in a variety of industries and applications. It has a high working efficiency of up to 96.5%, making it a great choice for applications that require a high degree of efficiency. It can be used in power supplies, motor control, and communications equipment, as well as in medical diagnostic equipment. Additionally, the XCL202B191ER-G is a RoHS compliant component, making it a great option for green manufacturing.

Working Principle

The XCL202B191ER-G DC-DC converter works through a control circuit, which is set up to ensure the output voltage is not lower than the input. The output voltage on the XCL202B191ER-G is adjustable from 0.6V to 32.8V, making it an extremely versatile converter. There are two components that are responsible for this adjustable voltage setting: the on-chip comparator and the pulse-width modulation (PWM) circuit. The on-chip comparator monitors the voltage across the output terminals. When the comparator detects a voltage that is lower than the reference voltage, it sends a signal to the PWM circuit. The PWM circuit then modulates the converter’s switching frequency to the desired level. In this way, the converter can regulate the output voltage and provide consistent power regardless of the input voltage.

The XCL202B191ER-G also has an on-chip current limit circuit that detects when the load current is higher than the rated value. Once it detects an overload, the current limit circuit will cut power to the load to prevent damage. Finally, the converter also features an auto-reset circuit, which will reset the converter after it has shut off due to an overload.

Conclusion

The XCL202B191ER-G is a versatile multi-output DC-DC converter that can be used for a variety of applications. It has a high working efficiency and is RoHS compliant, making it a great choice for green manufacturing. Additionally, the on-chip comparator, PWM circuit, current limit circuit, and auto-reset circuit help to ensure the stability and longevity of the converter.
