I'm interfacing a TFT display with MCU which requires 450mA current & 3.3V.
In power supply section I have used regulator ICs to get 5V & by using two diodes I'm getting 3.3V. For filtering in power supply I have used inductor.
but the display requires a 450 mA current which is not provided. & my display was getting reset because of not enough supply current. It led me to remove inductor & shorting it. now section is working & display is stable. But it will led to noise in power.
One remedy to this scenario I heard ( NOTE - I don't know exactly about it & I'm not sure Whether i'm saying it right. If it's wrong then please correct it) - we can use winding around an Inductor & then we can use it to provide enough current supply to display.
If any alternate solution is available with this please let me know.
NOTE - I'm not asking about how to regulate supply to 5V or 3.3V. I'm talking about the inductor which is used in filtering of power supply. How it is related to current if it is.
