POWER Requirements for a POWER SUPPLY

[jim2010]

Hi, Everyone:
After I designed a DC/DC power supply, I found that the power is a little smaller than the system requirements. The total power of my system is about 4 Watts, but the DC/DC supplier can only suppy 4.5 watts. I hope to know if there are some problems when I use this power source.

is it not 'power from supply is a little higher than system requirements?'

If it is higher, you definitely have nothing to worry about.

Maybe you could show me circuit?

I think this is very dangerous!
If the total power of your system is about 4 Watts, 6 watts ( 4 * 1.5 = 6 ) power to provide at least.

I think you need to be clear whether the power supply is higher power than the system or the other way round. Also, the voltage matters - are they the same voltage? Also, AC or DC?
