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, […]

The design of a Pulse Width Modulated Red-Green-Blue controller will be explained here. This design is efficient because this design uses multiple strings of six LEDs with a 24V DC source. This design is sufficient for a sizeable light because a total current of 2 Amps will supply 600 LEDs per color. The circuit below makes use of a remarkable […]

To operate, LED needs more than 1.5V voltage level. If you want to operate a LED with a single cell battery, you must boost the voltage to enable powering the LED. Here you can use two transistor circuit for boosting the battery’s voltage: The transistor shown in the schematic diagram is 2N3904 and 2N3906, but you can use other transistor […]
Read moreBelow 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 […]
Read moreBelow 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 […]
