CS5174GDR8

PMIC - Voltage Regulators - DC DC Switching Regulators

The CS5174GDR8 is a type of DC DC switching regulator which is classified under voltage regulators. It is specially designed for use in the application field of power management integrated circuits (PMICs) and is widely used in many electronic devices and machines. In this article, we will discuss the features and working principle of this DC DC switching regulator and how it is being used in the application field of PMICs.

Features

The CS5174GDR8 is a two phase DC DC switching regulator with a wide input voltage range of 4.5V to 46V. It has an integrated 57A power MOSFET, making it suitable for high power applications. The output voltage is adjustable from 0.8V to 5V. It also features a digital Soft-Start circuit and fault protection, which includes a low-side MOSFET short-circuit protection and an over-current/short-circuit protection with auto-recovery. Moreover, it also comes with an inverting buck-boost control phase compensation circuit and a must-on control phase compensation circuit, which will be discussed in the next section.

Working Principle

At the core of the CS5174GDR8 is the must-on control phase compensation circuit and the inverting buck-boost control phase compensation circuit. These two circuits work together to regulate the output voltage. The must-on control phase compensation circuit senses the input voltage fluctuations and compensates accordingly, while the inverting buck-boost control phase compensation circuit senses the output voltage fluctuations and compensates to ensure the output voltage is well regulated. These two circuits work together to ensure that the output voltage is regulated as desired, even with varying input voltages.

Applications

The CS5174GDR8 DC DC switching regulator is a perfect choice for applications that require a regulated power supply with a wide input voltage range and a wide output voltage range. It is especially well suited for use in power management integrated circuits (PMICs) such as PC motherboards, servers, storage systems, servers and telecommunication equipment. Additionally, it can also be used in battery-operated devices and in electronic products such as televisions, DVD players, cellular phones and other consumer electronic products.

Conclusion

The CS5174GDR8 DC DC switching regulator is a perfect solution for applications that require a regulated power supply with a wide input and output voltage range. With its integrated 57A power MOSFET and its digital Soft-Start circuit and fault protection, it is ideal for use in power management integrated circuits (PMICs) and other electronic products.
