Next buck converter inductor design formula will be for the DC current. But if you watch carefully on the buck converter schematic, the inductor is in series to the output load. Thus, the DC level of the inductor current is the same to the DC level of the load. This is the easiest de...
Calculating Minimum Inductance: Inductor current ripple is defined as the peak to peak change in current during the on and off time. For the synchronous buck converter, the change in inductor current during the high side MOSFET Q1 on time is equal to the change during the MOSFET’s off time...

For the converter, the typical output current is 500 mA. The HRTIM switching frequency is selected to have a PWM frequency of 250 kHz. A relevant estimation for the inductor ripple current is 30% typical of the output current value. For the buck mode, with a maximum of 15...
A new DC–DC buck–boost converter with a wide conversion ratio is presented in this paper. The proposed buck–boost converter consists of a combination of modified boost converter and ZETA converter, which has the advantages of both converters such as continuous input/output current and positive...
Variable Power Supply (Buck Converter): A power supply is an essential device when you are working with electronics. If you want to know how much power your circuit is consuming, you will need to take voltage and current measurements and then multiply th
The applied input current to a buck boost converter is the form of a pulsating current due to the switching of the associated power switch (Q1). Here the current switches from zero to l during every pulse cycle.The same is true for the output also and we get a pulsating current because...
