This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Lighting a string of LEDs at a constant brightness requires driving it with a regulated current. A boost converter is commonly used to step up the voltage to a level high enough to bias the LEDs on ...

This circuit provides latching and high-speed overcurrent protection for power-factor corrected (PFC) boost converters operating at dc voltages to 380 V. Overcurrent damage of PFC front-end boost ...

Combining the operation of a boost regulator and a negative voltage converter can generate a negative supply from a single low voltage supply. The circuit in Figure 5 shows a standard application ...

Controlling the brightness of LEDs requires a driver that provides a constant, regulated current. To achieve this goal, the driver topology must be able to generate a large enough output voltage to ...

Find a downloadable version of this story in pdf format at the end of the story. Boost power converters have been widely used for Power Factor Correction (PFC) in ac-dc conversions [1] and for power ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...

These days ready-to-use DC-DC converters are everywhere, with some of the cheaper ones even being safe to use without an ...
