I am looking for a DC-DC Boost/Buck converter chip solution and would appreciate your recommendation on a suitable model.
The specific operating conditions are: the input voltage ranges from 14V to 21V, requiring a stable output of 18V at 8A. Additionally,
I require the chip to have low heat generation during operation, minimal external components, and easy to design with.
Please recommend a suitable model based on these requirements. Thank you very much.

How many amperes of current can the three models you recommend respectively drive the MOS transistor to carry?
