Below is video tutorial about SMPS Buck Converter Design Example Part 1 of 2. Assume that Vin=12 V, Vout=5 V, Iload= 2A, Fsw=400KHz, D=Vin/Vout=0.416, Iripple=0.3 x Iload. Now we can calculate the magnitude of the inductance. Since inductance (L)= (Vin-Vout)x(D/Fsw)/Iripple we get the inductance is 12.12uH. On this video also explained aboutbuck convertercalculate output capacitance, buck converter select output capacitor, […]

This is simple isolated power supply video. This video shows step by step how to design isolated power supply. The simple isolated power supply adalah flyback topology. This topology is chosen because it s safety, has a little noise and the unit production. This video focus on the flyback topology. In flyback topology, the transformer s used in two purpose,they […]

Below is video tutorial about how to design a complex switching regulator as simple as a linear regulator – Linear Technology. Linear regulator is very simple. Linear regulator circuit has no inductor and built using a very few component and use for low power application. For higher application, we can use monolithic switch-mode regulators. This regulator has more component than […]

Below is a video tutorial about Analog Semiconductors: Designing with Data/Audio Switches. An electronic products such as iPhone or MP3 now have USB and headphone combine in one plug. On this video explained about how MP3 can have only one plug for USB and headphone and how the switch work. As we know that the codec has narrow bandwidth about […]
