LNBP10LPUR is an integrated circuit (IC) specially designed for voltage regulators. It is a special purpose PMIC, and its application field and working principle is an important topic to be discussed.

Application Field of LNBP10LPUR

LNBP10LPUR is particularly suitable for applications with high voltage and current stress requirements. It is an ideal solution for medium power applications with its wide operating temperature range, low quiescent current consumption, and high voltage output. It can be used for personalized desktop power supplies, mobile power supplies, infotainment systems, power tools, LED drivers and consumer electronic field applications. LNBP10LPUR also provides a pulse-by-pulse protection feature that prevents its outputs from being destroyed due to faults and transient events.

Working Principle of LNBP10LPUR

The operating principle of this IC can be divided into two parts: Regulation Mode, and Error Amplifier Mode. The regulation mode has two distinct modes, either a fixed or adjustable voltage mode, and includes features such as over current protection and short circuit protection. The adjustable voltage mode allows the IC to control its output voltage by adjusting the current load on the input lines. The error amplifier is used to monitor the output voltage and compare it to the desired voltage. If the output voltage is too high, the error amplifier will reduce the current load on the input lines, which in turn reduces the output voltage. Conversely, if the output voltage is too low, the error amplifier will increase the current load on the input lines, resulting in a higher output voltage.

Conclusion

LNBP10LPUR is a special purpose PMIC designed for voltage regulation applications. It is particularly suitable for applications with high voltage and current stress requirements, and can be incorporated into mobile power supplies, infotainment systems, power tools, LED drivers, and consumer electronic field applications. It has two distinct operating modes, a fixed or adjustable voltage mode, and includes features such as over current protection and short circuit protection. Finally, its error amplifier can monitor the output voltage, compare it to the desired voltage, and make adjustments accordingly.
