Hi everybody.
I haven't visited the forum from a long time, hope you are all fine.
I want to design a step-down DC-DC converter with input voltage range 24V~32V and any output between 20V and 24V, say 22V assuming a dropout voltage around 1V. The output current is actually high, it is 5A at minimum, and may be I'll need it up to 10A.
For this high current I think I'll need a buck controller IC and use external MOSFETs.
I don't want to use expensive parts (ex. not more than 5$ for the IC). Also I'm limited with the availability of parts here. There are 10A Simple Switcher power modules that my fit my need, but these aren't available here.
"The newest additions to the SIMPLE SWITCHER® power module family feature load currents up to 10A, frequency sync, current sharing, and pin-to-pin compatibility to deliver an entire portfolio of ease-of-use solutions."
See this reference: http://www.ti.com/ww/en/simple_switcher_dc_dc_converters/index.html
The efficiency isn't very important in this case, but I don't want to use linear regulation!
What do you recommend?
Thank you and Happy New Year!
