Buck-boost converters are a form of switching-mode power supply that can supply a regulated DC output from a source voltage either above or below the desired output voltage. This can be particularly ...

Buck-boost converters produce a regulated output voltage either less than or greater than the input voltage. When the input voltage is higher than the output, the converter acts as a buck. When the ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...

The drive to increase efficiency and reduce the size of switching power supplies has proliferated into just about every aspect of industrial, consumer, and lighting electronics. The simple step-down ...
