Dear Sir/Madam,
I am going to develop a multi-input DC/DC converter. The system diargra is shown below:
It is clear that one input source is DC power and the other is AC power. The DC input is actually a 22-30VDC power bank. So I am thinking the other AC input can be converted to 30VDC by a simple AC/DC converter as shown below:
Since the output is fixed 9V which is always lower than input 22-30VDC, then I would like to use a simple buck topology to implement the main part of this multi-input DC/DC converter. Or buck-boost topology is acceptable if required.
But my question is, are there any recommend controller chips which can support multi-input function? Or is there any recommended way to implement multi-input function in this system?
any opinions or suggestions are welcome. Thank you all.
