LM25117QPMHE/NOPB is a type of PMIC (Power Management Integrated Circuit) voltage regulator, which is known as a DC DC switching controller. This type of voltage regulator is designed to regulate the output voltage of the power supply by utilizing both a buck converter and a boost converter. The LM25117QPMHE/NOPB application field and working principle is further described below.

LM25117QPMHE/NOPB Application Field

The LM25117QPMHE/NOPB voltage regulator is used in applications where efficient DC to DC power conversion is required. This is especially helpful in battery-powered products such as mobile phones, portable medical and health products, IoT (Internet of Things) products, and PC peripherals. The LM25117QPMHE/NOPB is equipped with two integrated regulators to provide a wide range of regulation possibilities for both step-down (buck) and step-up (boost) applications. This makes it especially suitable for power systems that require sequential step-down and step-up operations, where a high performance is required and minimal board space is available.

LM25117QPMHE/NOPB Working Principle

The LM25117QPMHE/NOPB voltage regulator utilizes DC-DC converters to provide a regulated output voltage. It uses a buck converter for step-down voltage regulation and a boost converter for step-up voltage regulation. When the output voltage is low, the buck converter regulates it by drawing only the necessary amount of current. Similarly, when the output voltage is higher than required, the boost converter is employed to reduce the excess voltage. In addition, the on-board current-mode PWM (pulse width modulation) controller enables the circuit to work with a wide range of input and output voltages, which makes it highly suitable for multiple applications.

The LM25117QPMHE/NOPB also has built-in features such as over-voltage, under-voltage, over-current, and over-temperature protections. These features are important for safety and reliable operation, and help to prevent any potential damage or malfunctioning of the system due to improper handling. Additionally, the LM25117QPMHE/NOPB voltage regulator also has a low quiescent current and low ripple to maintain a low noise operation.

Conclusion

The LM25117QPMHE/NOPB is a DC-DC switching controller that is highly suitable for multi-level voltage regulation applications. Its integrated buck and boost converters, along with its built-in safety features, make it a great choice for a variety of power systems. Furthermore, its wide range of input and output voltages, combined with its low quiescent current and low ripple, allow it to provide a high performance, low-noise operation that is ideal for battery-powered products.
