DC-DC converters are an essential element of any power system. They convert voltages from one level to another as required for various applications, enabling efficient and stable power delivery. The CHS2004812-U DC-DC converter is one such high-performance and versatile device, designed to be used in a variety of applications. This article looks at the application field and working principle of this device to get a better understanding of how it works.
Overview of the CHS2004812-U
The CHS2004812-U is a two-stage DC-DC converter designed to perform 48V to 12V conversion efficiently and reliably. It features an external MOSFET which helps drive the SMPS output, as well as an integrated active-clamp, an internal current sense and transconductance loop. It is available with high-performance conversion ratings of up to 8A and 30W, and can easily outperform competing solutions in terms of efficiency, reliability, and cost.
Applications
The CHS2004812-U converter is particularly suited for two application markets. The first is automotive and transportation, where the device is used for 12V and 48V power supply systems. It can be installed in vehicles such as cars, buses, and trucks, and helps maintain the power supply to different onboard systems such as navigation units, audio systems, and inverters. The second application market is industrial, where the device is used for 12V and 48V power supply systems in robotics, automation, and other factory applications requiring a reliable and efficient source of power.
Working Principle
The CHS2004812-U converter uses a two-stage topology to convert 48V DC input to a 12V DC output. In the first stage, also known as Power Stage, a converter-design-and-simplified-power-stage-diagram MOSFET semiconductor switch is used in combination with other external components to generate a desired voltage level across the output inductor. The second stage is the Control Stage, wherein the output voltage is regulated by an internal active clamping circuit, a current sense, and a transconductance loop.
In the Control Stage, the active clamping circuit senses the output voltage and adjusts the current applied to the external MOSFET. This allows the device to maintain a stable output voltage regardless of input voltage, load variations, and temperature changes. The current sense, on the other hand, detects the current in the feedback loop and adjusts the feedback loop to the proper gain as necessary. Lastly, the transconductance loop adjusts the output voltage, allowing the device to reach the desired output voltage in a short amount of time.
Conclusion
The CHS2004812-U is a powerful and versatile DC-DC converter designed to convert 48V DC to 12V DC efficiently and reliably. It can be used in a variety of applications, such as automotive and transportation, and industrial applications, providing an efficient and cost-effective power solution. Its two-stage topology also helps ensure that the device performs with excellent stability, enabling it to regulate the output voltage regardless of input voltage, load variations, and temperature changes.
