CQS24120-12

DC-DC converters are devices used to convert a voltage from one level to another. The most common type of converters is the step-down, which can be used to convert a high-voltage input voltage into a lower, more easily managed output. The CQS24120-12 is a common type of DC-DC converter, and is primarily used for intermediate or distributor power supplies.

The CQS24120-12 has a maximum input voltage of 24V, and a maximum output voltage of 12V. This makes it well suited for applications requiring intermediate voltage, such as battery chargers or voltage regulators. The CQS24120-12 also has a wide range of working temperature ranges, but is typically best suited for applications where the temperature range is between -20°C and 40°C. The device is also capable of handling extremely high voltages, up to 100V.

The CQS24120-12 has a high efficiency rating, typically around 92%, and is considered one of the most reliable DC-DC converter models on the market. This is due to its robust design, which includes low standby current leakage and low temperature coefficient to ensure consistent performance. The device also has a very low ripple and noise rating, making it great for applications where precise control of the output is required.

The CQS24120-12 has a switching frequency of 3 to 5 MHz, and a working current of up to 15A. This makes it ideal for high current applications such as voltage converters, motor controllers, and even remote power systems. Additionally, the device has a wide range of protections, including overcurrent, overtemperature, and overvoltage protection. This makes it well suited for applications where safety is a priority.

In terms of its working principle, the CQS24120-12 works by using two drives, a high and low side, and inductor and two capacitors to create a buck converter. The inductor stores energy as it passes from the input voltage to the output, and the capacitors filter the various harmonic frequencies. As the input voltage changes, the driver quickly switches from the high to the low side, providing high efficiency conversion without any significant losses in power.

Overall, the CQS24120-12 is an excellent choice for applications requiring intermediate level voltage conversion. Its robust design ensures reliable performance, and its wide working temperature range makes it an ideal choice for a variety of applications. In addition, its switching frequency and high current capacity make it great for applications requiring precise power regulation, and its range of protections make it suitable for safety-critical applications.
