Interfacing an external +5V power supply with Raspberry Pi Pico
From the section 4.5 Powering Pico of the official Raspberry Pi Datasheet. I have decided to use the first method which is suggest to use a schottky diode with the VSYS pin. I have used 1N5819 Schottky diode.which hasVRRM = 40V,Maximum average forward rectified current IF(AV) = 1A The schottky diode and the diode on…

15V Unregulated DC Power Supply using 12Vrms step-down transformer
There are two ways to make DC power supply Linear Switching Linear Power SupplyContinous control of voltage is done at any instance of time. It uses a pass transistor with an error amplifier to regulate the voltage supply.example: 7805, 7905, LM317 etc Switching Power SupplyIt also uses the pass transistor along with an inductor and…
