Buck converter design is never easy. There are lots to consider ensuring a robust design. The components must be selected well and ensure sufficient design margins. However, this is difficult no more with the use of this synchronous buck converter excel design template.
This design template is made in excel format. Thus everyone can use this. This is very handy and yet powerful design tool. Below is simple tutorial on how to use this synchronous buck converter excel design template.
Synchronous Buck Converter Excel Design Template Legends
All the orange fields are inputs. Meaning, user can put the values in these fields. On the other hand, all the fields in green are computed values. Do not alter them.
Synchronous Buck Converter Excel Design Template Main Sections Definition
Design Given, Duty and Period
All the design given needed are asked in these section. There is a description in each item for easier understanding of the user. Just enter the values and let the template do the works for you.
Under this section, all parameters related to the inductor are computed. Take note that there are few inputs needed in this section as well. Supply them with the correct values for the template to work correctly.
Upper Switch Calculation
The upper and lower switches are internal to the controller. The values computed must be compared to the IC datasheet. There are few inputs needed in this section to work properly. Fill them.
Lower Switch Calculation
Same with the upper switch, the lower switch is internal to the controller. The values computed here must be compared to the IC datasheet. Also, enter the input values asked here.
Output Ripple Analysis
This section helps the user in selecting the right size output capacitor. It also illustrates the ripple current of the capacitor.
This design template is derived carefully and checked through other means like simulations and actual projects. After downloading this Synchronous Buck Converter Excel Design Template and have trouble understanding, contact [email protected].
