So why roll your own buck-boost converter for the ground up? Maybe because sometimes the best way to learn is by doing. When it comes to clear and succinct explanations, [GreatScott!] has you covered.

Finally, an inverting buck-boost converter places additional voltage and current stresses on the power devices compared with a four-switch buck-boost circuit, reducing relative efficiency.

Figure 1 shows the schematic of a synchronous buck converter. The circuit replaces the diode in the basic buck circuit with a low-side (LS) FET chosen for low R DS (ON).

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

A high-efficiency buck-boost DC-DC converter was developed by the research team headed by Prof. CHENG Lin from the School of Microelectronics at the University of Science and Technology of China ...

Even though buck converters, and other DC converters like boost and the mysterious buck-boost converter, seem like magic even to us, there is some interesting electrical theory going on if you ...

The buck-boost converter in Figure 1 uses an Elantec EL7515 pulse-width modulation (PWM) step-up dc-dc regulator that incorporates an internal NFET switch, with the drain connected to the LX pin ...

This topology is also known as a fly-back orinverting regulator. A buck-boost converter can be implemented as shownin Figure 1 above. This implementation has the advantage that a simple, low-side ...

ROHM has released a buck-boost DC/DC converter with integrated MOSFET, the BD83070GWL, that combines efficiency with best-in-class current consumption, making it suitable for IoT, wearables, and ...
