Buck Converter Regulator FAQ

What is a buck boost regulator?

Buck-Boost Regulators. Supporting up to 3 A of operating current, ST’s single-inductor synchronous buck-boost converters integrate four low on-state resistance power MOSFETs which contribute to PCB saving and reduced power losses, making them ideal for Li-ion battery-powered applications. The main features of our buck-boost regulators include:

What is a buck regulator?

A buck converter also called buck regulator or DC-DC step-down switching regulator, is a type of DC-DC converter which provides an output regulated voltage that is lower than its input voltage. ST's monolithic step-down (buck) converter ICs offer input-voltage capability up to 61 V, deliver output currents up to 4 A, with high switching frequency.

What is a buck controller?

DC/DC step-down (buck) controllers with external FETs give designers the ability to optimize their power supply for even the most challenging requirements. With buck controllers, power-supply designers can reach levels of output power, operating temperature range, and voltage step-down ratios that are simply not possible with converters or power modules.
