The CS5161HGDR16 is a Special Purpose Voltage Regulator, part of the PMIC (Power Management IC) family of voltage regulators. It is designed to provide a flexible, unregulated voltage supply that is programmable to a variety of different voltage levels, making it suitable for a wide range of applications. In this article, we’ll discuss the application field of the CS5161HGDR16, and its operating principle.

Application Field

The CS5161HGDR16 is designed with a wide range of applications in mind. It is a very versatile voltage regulator and is suitable for both industrial and commercial applications. For example, it is commonly used to power up or regulate various high-power and precision devices, such as Industrial PCs, Industrial Robots, Automation Controllers, Network Appliances and Professional Surveillance Systems. This voltage regulator is also useful for critical electrical applications such as Automotive Lithium-ion Battery Pack Power Systems, Inverters, Servo Motors and other types of high-power industrial applications.

The CS5161HGDR16 is also suitable for use in server applications. It provides a stable, low-noise voltage supply, essential for server and storage applications. This voltage regulator can also be used in medical device applications, as it is certified to meet EN 62368-1 safety requirements. In addition, it is available with optional remote sense feature, which allows the device to quickly respond to voltage drop and ensure that the device is supplied with desired voltage.

Working Principle

The CS5161HGDR16 is based on a Switching Regulator (SR) topology. It utilizes a pulse-width modulation (PWM) control scheme to convert a given input voltage into the desired output voltage. The CS5161HGDR16 consists of a Pulse-Width Modulator (PWM) block, an Error Amplifier (EA), and a section for voltage reference and feedforward. The PWM block compares the output voltage with a reference signal from the Voltage Reference and Feedforward section, and then sends the error signal to the Error Amplifier (EA) block. The EA outputs a control signal to the PWM block to adjust the duty cycle of the output Power MOSFET, so that it maintains the output voltage within the specified limits.

The CS5161HGDR16 provides a wide range of output voltage options, with 24 different adjustable settings ranging from 0.5 Volts to 5.5 Volts. The output voltage can be set by using an external voltage divider, or by using the Voltage Programming port. Additionally, it has a ±1% output voltage accuracy, which makes it suitable for even the most exacting applications. Furthermore, the CS5161HGDR16 has an operating temperature range of -40 °C to +105 °C, and it can operate with relative humidity of up to 85%.

Conclusion

The CS5161HGDR16 is a Special Purpose voltage regulator from the PMIC (Power Management IC) family. It is designed to provide a flexible, unregulated voltage supply that can be programmable to a variety of different voltage levels, making it suitable for a wide range of applications. Its versatile feature set and wide temperature range, as well as its precision output voltage accuracy and optional remote sense feature make it a great choice for industrial, commercial and even medical applications.
