LP8755KMX/NOPB is a two-phase Direct Current (DC) Switching Regulator designed for non-isolated point-of-load (PoL) regulated power supplies. The circuit is designed to operate with a wide input voltage range of 4.5V to 70V, and is able to provide a continuously regulated output voltage of 1.2V to 12V with a maximum output current of 8A. It comprises two high-side power MOSFETs, two low-side power MOSFETs, a synchronous rectifier, and a control/protection IC. These components work together to efficiently manage power transfer from the input to the output, thereby regulating the output voltage.

The main application field of LP8755KMX/NOPB is DC/DC power conversion and system power management solutions. Thanks to its wide input voltage range and excellent efficiency, the LP8755KMX/NOPB is suitable for a wide range of industrial, automotive, and consumer applications, including power supplies for servers, storage, computing, and networking applications; power management solutions for digital home appliances (such as HVAC, refrigerators and smart TVs); power supplies for automotive systems (such as sensors and displays); and power management systems for medical and other industrial equipment.

The working principle of the LP8755KMX/NOPB is based on a two-phase, current-mode PWM (pulse width modulation) control scheme that enables fast transient response, excellent line and load regulation, and constant voltage/current operation. The IC has an integrated high-side and low-side MOSFET driver to control the switching of the power stage, and an internal compensation network and current sense amplifier to control the current through the power MOSFETs. In addition, the IC also contains comprehensive protection and fault protection features, including overvoltage protection, thermal shutdown, and overcurrent protection.

The LP8755KMX/NOPB\'s two-phase PWM control scheme optimizes the power stage design, reduces circuit complexity and board space requirements, and reduces overall cost. The two-phase implementation helps to uniformly share the peak inductor current between two phases, reducing the stresses on components and improving overall efficiency under heavy load conditions. The control IC also features multiple user-configurable configurations and settings, such as switching frequency, soft-start, overvoltage protection, undervoltage protection, and overcurrent protection. This enables designers to customize the LP8755KMX/NOPB for their application needs.

In summary, the LP8755KMX/NOPB is a two-phase Direct Current (DC) Switching Regulator designed for non-isolated point-of-load (PoL) regulated power supplies. The main application field of LP8755KMX/NOPB is DC/DC power conversion and system power management solutions, and its two-phase PWM control scheme enables fast transient response and excellent line and load regulation. The IC has an integrated high-side and low-side MOSFET driver to control the switching of the power stage, and comprehensive protection and fault protection features. This makes it suitable for a range of industrial, automotive, and consumer applications.
