LT8601EUJ#PBF Application Field and Working Principle

The LT8601EUJ#PBF (Reversing Buck-Boost Switching Regulator) is a high-power DC switching regulator (PMIC - Voltage Regulators - DC DC Switching Regulators) manufactured by Linear Technology Corporation. The LT8601EUJ#PBF provides a high-performance and power efficient solution for applications that require an adjustable output voltage over a wide input range, such as solar systems, hybrid electric vehicles, and industrial applications.

The LT8601EUJ#PBF is designed to achieve a high power efficiency and maximum power transfer over a wide input range. The device operates in synchronous Buck-Boost mode, which enables higher power efficiency compared to non-synchronous mode operation. The device is capable of supplying up to 4A of output current and its unique architecture allows for a wide input voltage range from 3.5V to 36V. The output voltage can be adjusted from 0.8V to 5V using an external resistive divider network.

Working Principle and Application

The LT8601EUJ#PBF is a reversibly synchronous buck-boost switching regulator that converts a wide input range of dc voltages into an adjustable output voltage. The buck-boost method enables higher power efficiency compared to non-synchronous mode operation.

The LT8601EUJ#PBF operates by first regulating an internal voltage which is between the input and the output voltage. When the system voltage is rising, the device will act as a buck regulator and switch from the input to the internal reference voltage. When the system voltage is dropping, the device functions as a boost regulator and switches from the output voltage to the internal reference.

The LT8601EUJ#PBF can be used in multiple applications where an adjustable output voltage is required over a wide input voltage range. Some of the common applications include solar systems, hybrid electric vehicles, industrial systems, and other high power DC applications.

The LT8601EUJ#PBF provides the high efficiency and power output needed for these applications. With its unique architecture, the LT8601EUJ#PBF can provide up to 4A of output current and is able to operate with very low inductor ripple current and minimal losses. The output voltage can be easily adjusted using an external resistive divider network.
