Introduction

CS5172EDR8 is a switching regulator which is in the family of DC/DC voltage regulators. It is designed for low voltage applications including the mobile devices and automobile products. This switching regulator includes two linear power stages which provides higher efficiency than other traditional solutions. It offers up to 95.6 % efficiency, allowing smaller components and lower on-resistance which ultimately achieve high performance voltage regulation.

Application Field

The CS5172EDR8 is mainly used for providing a regulated output voltage from a wide input voltage range in various applications. These applications include mobile phones, tablets, car radios, and automotive electronics. The regulated output is also commonly used for powering low voltage integrated circuits, such as ARM® Cortex®-M4 processors.

This switching regulator can also be used in application like battery powered handsets and other portable devices, where low quiescent current (typically 0.5mA) is equally important. Additionally, the high rated output current which reaches up to 2A and the fast transient response of the regulator make it suitable for powering GPUs and other ASICs where high current and fast transient response times are required.

Working Principle

The CS5172EDR8 switching regulator works on a two-stage architecture which consists of a main power stage and a linear power stage. The main power stage consists of a P-channel MOSFET and an N-channel MOSFET and is used to control the power flow. This power stage is controlled by a switching frequency which is constant and it is flexible to choose between two different topologies. The main power stage is then followed by a linear power stage, which is used for filtering the output voltage and for providing a controlled ramp signal for setting the output voltage. The linear regulator is a low drop-out regulator which operates in diode or transistor mode. To limit the input or output current of the regulator, external resistors can be connected to the current sense pin, which then results in the current protection of the system.

The CS5172EDR8 provides all the features required for a reliable, robust and high performance regulator for low voltage applications. This regulator has high efficiency and low quiescent current as well as fast transient response, which makes it ideal for powering applications like GPUs, CPUs, and ASICs. Furthermore, the product is also RoHS compliant and AEC-Q100 certified.

Conclusion

The CS5172EDR8 is a highly efficient and reliable switching regulator designed for low voltage applications. It can easily convert input voltage from wide range and output a regulated voltage. This regulator offers features like high efficiency, low quiescent current, fast transient response and current protection, making it the ideal regulator for low voltage applications.
