WebA switching regulator works by taking small chunks of energy, bit by bit, from the input voltage source, and moving them to the output. This is accomplished with the help of an electrical switch and a controller which regulates the rate at which energy is transferred to the output (hence the term “switching regulator”). WebSelecting a buck regulator to convert to an IBB requires special attention to the voltage and current requirements of the application. A quick glance at Figure 4-1 shows that the voltage across the VIN and GND pins of the regulator IC is equal to the input voltage plus the negative output voltage. This voltage is greater than for a buck china cuisine grimsby menu
