The NB6381DL-LF-P is a member of a family of switch mode voltage regulators and is part of Power Management ICs (PMICs) that provides efficient control of a broad range of applications. This product belongs to the class of DC DC Switching Regulators, featuring a wide input voltage range, low output ripple and quiescent current for high efficiency. The NB6381DL-LF-P is especially designed for low temperature and low power operation, providing voltage regulation for Mobile Market Application, Battery Powered and Low Power Display Applications.

Application Field

The NB6381DL-LF-P is mainly used for system power supply and battery-powered displays, as well as in lighting, computers, telecommunications, and consumer electronics fields. It is capable of achieving a high power efficiency with a wide input voltage range, low output ripple and quiescent current. The NB6381DL-LF-P has current limitation and short circuit protection to ensure the safety of the device and the system it is connected to. It also supports two independent output voltages with different voltages, which can be adjusted by internal trimming, ensuring the user has the best possible regulation performance.

Working Principle

The NB6381DL-LF-P consists of an energy storing inductor, an energy storing input capacitor, and a smoothing capacitor. It operates in a pulsed mode, where the switch is opened and closed at a rate corresponding to the input voltage, adjusting the duty cycle to maintain the desired output voltage. When the switch is closed, current flows into the inductor and reaches a peak value as the inductor’s energy is constantly stored during the on-time. After the switch opens, the inductor’s current begins to decrease, reaching a minimum value when the switch is again closed. The energy stored in the inductor is then released into the output capacitor, providing a steady output voltage.

The NB6381DL-LF-P also has integrated safety features such as current limitation and short circuit protection, which protect the system from excessive current and temperature. In addition, the device has adjustable multiple output voltages and an over-voltage protection that prevents the output voltage from exceeding the designed voltage.

Thanks to its combination of high efficiency, wide input and output voltage range, and integrated safety features, the NB6381DL-LF-P is the perfect voltage regulator for low temperature, low power applications. It ensures the ultimate performance, safety, and reliability of a system while consuming minimal power and providing maximum efficiency. Therefore, the NB6381DL-LF-P is an ideal choice for modern power management applications.
