A Buck-Boost DC/DC converter is a non-isolated switching DC power topology whose output voltage can be either lower or higher than the input voltage, and it can also output reverse polarity voltage. It combines the step-down function of Buck and the step-up function of Boost, achieving stable voltage output when the input voltage fluctuates above or below the required output voltage.
Application Scope：
1.Battery-powered devices with wide voltage fluctuation,such as lithium battery single-cell or multi-cell power supply systems.
2.Scenarios where the input voltage may be higher,equal or lower than the fixed output voltage.
3.Consumer electronics,portable instruments,industrial control modules and IoT devices.
4.Automotive electronics,solar power supply systems and low-voltage distributed power systems.
5.occasions requiring negative voltage power supply for analog circuits and operational amplifier circuits.
