Buck Converter Basic Function Before going to buck converter design tutorial, we will discuss first how buck converter works in order to fully understand the following tutorial. A buck converter is a switching converter with a voltage output lower than voltage input. It is also called as a step-down switching converter. A buck converter has only four main parts. They

One of the most important parts of a buck converter is the inductor. Sizing the inductor of buck converter and setting its operation mode makes the converter function correctly. The shape and the magnitude of current of the inductor are dictated by the inductance of the inductor itself. Therefore choosing the right inductor value is very important. Sizing the inductor

In this article I will share to you the methods I used in buck converter duty cycle derivation. We will consider the ideal and the real scenarios. In ideal buck converter duty cycle derivation, you don’t need to consider the voltage drops of the switching element and catch diode. On the other hand, in real buck converter duty cycle derivation,

This design reference is for 7V to 25V input with 5V and 1.5A output buck converter using LT1376-5 controller. LT1376-5 is monolithic buck mode switching regulator which has a fixed frequency of 500 kHz. The switching element is internal on the controller thus lower component count. The internal switch can able to handle 1.5A current. The controller can be used with
