Part Number: LMR54410
Hello, the diagram for our circuit using the integrated circuit LMR54410DBVR is shown in the image below.
When the circuit has to be powered by 5 volts (USB, via connector J1), there is still a diode D10 adding a drop of approximately 0.4 volts.
According to the regulator's datasheet, we see that the input voltage range is between 4 and 36 volts.
In the case of the main supply being 5 volts, with the drop provided by the diode (0.4 volts), we will have approximately 4.6 volts at the regulator's input (disregarding other factors). With this input voltage value (4.6 volts), will the LMR54410DBVR circuit work perfectly, generating the intended output voltage of 3.3 volts?
Thank you.
