When a buck regulator is used for a polarity-inverting topology, the regulator IC ground is attached to the system output voltage, and the inductor is connected to the system ground voltage. The ...

A buck-boost circuit with an ADP2386 buck regulator is depicted in Figure 2.If a buck-regulator IC is used for the inverting circuit, the ground connection of the IC is at the generated negative ...

Figure 9. Combining buck and boost circuits with LDO regulators for USB-powered devices . In summary, the combined buck and charge pump topologies and circuit ideas presented can provide high ...

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.

Synchronised boost-buck (?) Anyway, Ayyanar points out that: if a boost converter is fed directly into a buck converter (sharing the boost output capacitor as the buck input capacitor – see diagram ...

1. Simplified diagram of the LTM8055; the LTM8056 is similar except for the value of its output capacitor. The LTM8055 and LTM8056 are standalone non-isolated buck-boost switching DC/DC power ...
