LNBH21PD is a high-performance, high-efficiency, multi-output voltage regulator with integrated MOSFETs. It is typically used in applications that require high efficiency and low dropout (LDO) linear regulation of power supplies. This device combines a low-voltage LDO and a high-voltage voltage regulator with integrated MOSFETs to provide high efficiency and power conversion. It can reduce system power consumption by more than 10%.

The LNBH21PD is designed to provide a fixed voltage output over a wide input voltage range. The integrated MOSFETs enable variable switching frequency operation to reduce EMI. The regulator can also operate as a wide input range variable output voltage regulator with external feedback resistors. The integrated step-down/step-up voltage regulation provides a constant voltage output for applications requiring low ripple and low noise.

The LNBH21PD is suitable for a wide range of applications including mobile phones, laptops, LED lighting, automotive systems, and point of load (POL) applications. It also provides high efficiency and high power conversion, making it an ideal solution for applications where power consumption is a major concern. It is especially useful in applications that require a large number of outputs with different voltage requirements.

The working principle of the LNBH21PD is based on the buck converters. The device works by converting an input voltage into desired regulated output voltage with maximum efficiency. The output voltage is regulated by the internal voltage reference, which is set by external resistors. The power switch within the LNBH21PD is usually driven by a dedicated current sense comparator, which is used to regulate the output voltage as well as to perform power management tasks.

The LNBH21PD has two integrated MOSFETs: one for controlling the input voltage and the other for controlling the output voltage. Both MOSFETs are responsible for driving the power consumption within the device, providing efficiency improvements. In addition, the device offers multiple protection features, including thermal shutdown and over voltage protection. It is packaged as a small 14-pin SOIC (Small Outline Integrated Circuit) with a low profile for easy integration.

The LNBH21PD is an ideal solution for applications that require flexibility and adjustable output voltage ranges. The integrated MOSFETs provide improved efficiency and reduced EMI. The device is easy to integrate with other power circuits and offers multiple protection features to ensure system reliability and stability. The device is suitable for use in low voltage and high voltage applications, while offering significant power savings.
