This application note covers the steps required in choosing the inductor and to calculate the value used in buck regulator IC circuits. Switching regulators are used in a variety of applications to ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

To illustrate the factors that play a role in a buck converter’s efficiency, the Table below lists the equations used to estimate the most significant power losses. The parameters to minimize for high ...

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 ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...

Synchronous buck converters have received great attention in low power, low voltage DC-DC converter applications in recent years due to their high efficiency. International Rectifier Inc. has ...

Step-down (buck) voltage regulators have long been the preferred DC-DC conversion electronic workhorse thanks to their inherently high efficiency. Only in buck mode the current is directed to the ...
