Hi,
I am making a circuit board where two voltages are needed:
Do you have any recommendations on circuits to use for power regulation?
I have looked at the National Semiconductor SIMPLE SWITCHER LMZ12003. Space-wise, I have just enough room to fit two circuits using these (one for 3.3V and one for 5V) on my board. Does that sound reasonable? I have also considered just using the LMZ12003 for 3.3V and then using a boost regulator (LT1935) to get the 5V needed for USB - is that a better approach?
Thanks for your feedback!
I am making a circuit board where two voltages are needed:
- 3.3V, to power 3 microcontrollers. Probably around 1.2A
- 5V, to power a host USB port and one IC. Probably around 1A
