LM5175-Q1 is a synchronous four-switch buck-boost DC/DC controller with wide input voltage range, adjustable switching frequency, and various protection features.
The LM5175-Q1 is a synchronous four-switch buck-boost DC/DC controller capable of regulating output voltage to a value higher or lower than the input voltage. It operates over a wide input voltage range from 3.5V to 42V (maximum 60V) and supports an output voltage range from 0.8V to 55V. The device utilizes current-mode control in both buck and boost modes for excellent load and line regulation. This manual is written in Chinese.
