Hello , I am looking for a recommendation for an Adjustable buck converter with an output range of 5 to 15V and an input voltage of 24 V which also supports up to 4 or 5 Amperes. I want to add a digital potentiometer to control the output voltage. I found many ICs including TI tps5450 but when changing the output voltage from 5 to 15 many design elements have to be changed such as the inductor and capacitor values Not only the resistor as I desire.
Do you know any recommended ICs for this purpose? Thank you very much!
 

Hi,

Read the datasheet thorouhgly, read application notes.
Inductors and capacitors have a "range" not a fixed value. The values are recommendations.
One may optimize for low cost, or low ripple, high efficiency....

Usually datasheet give min and max value informations.

yes indeed after carefully reading the data sheet I found out that I can use higher values than calculated. Thank you
