This document is an engineering report describing a non-isolated buck-boost (inverting) power supply utilizing a LNK306P. This power supply is intended as a power supply for an appliance application.

Several power supply topologies, including SEPIC and flyback converters [1], generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the ...

What are the three main non-isolated topologies? What to consider when designing high-voltage apps using the inverting buck-boost. Other design considerations when dealing with even higher voltages.

Use of buck-boost circuits in switching-regulator ICs. Considerations in level-shift circuit design. Switching regulators with internal level shifting. The magnitude of the negative voltage generated ...
