LT8631IFE#PBF is a monolithic integrated circuit applying to DC-DC switching regulators. It combines high switching frequency and high efficiency for various buck and boost regulators. The device features an internal dc ush circuit including an N-Channel MOSFET driver that operates from a single 4.5V to 32V supply. The LT8631IFE#PBF is available in a tiny 8-Lead MSOP/DFN package.

The LT8631IFE#PBF offers a wide range of switch mode regulators such as buck converter, boost converter, buck-boost converter and SEPIC converters. Its excellent characteristics make it suitable for a wide range of mobile and battery powered applications such as laptop, cellphone, and other handheld devices.

The working principles of switching regulator are use of high frequency transistor switches and an inductor to convert the input voltage to desired output voltage. The switching regulator increases the voltage (boost), decreases the voltage (buck) or does both.

The LT8631IFE#PBF provides a fast current mode PWM control with 360 kHz frequency, which enables high efficiency and fast transient response for various buck, buck-boost and boost applications. The switching regulator provides automatic Burst Mode operation, skip mode and Pulse-Skipping operation that provide low quiescent current operation which is perfectly suitable for battery-power mobile applications.

The LT8631IFE#PBF features a current mode PWM control with an adjustable soft-start. The device is protected by over current, over voltage and over temperature to ensure a load is safely regulated. The UVLO feature ensures the device is operated in a safe operating range in all conditions.

LT8631IFE#PBF switching regulators also feature a wide input voltage range of 4.5V to 32V, very low rippple, high efficiency and fast transient response. The integrated feedback control and compensation ensures accurate current limit, output voltage and wide load range control. In addition, the device supports a wide variety of control, programming, and protection functions.

In summary, the LT8631IFE#PBF is an integrated monolithic IC for various DC-DC switching applications such as buck, buck-boost and boost. It features fast current mode PWM control with 360 kHz switching frequency, high efficiency and fast transient response. The device also includes several protection and control features in a very compact 8-Lead MSOP/DFN package. The LT8631IFE#PBF is suitable for mobile, battery-powered and hand-held applications such as laptop and cellphones.
