Power supply design issues.
Budget: $30 – $250 USD
I have a battery backed power supply circuit. Block diagram attached.
5 - 12v DC input (VIN) which charges battery as well as supply power to dc/dc converter. to switch between battery and VIN im using a P-CH mosfet DMG3415U-7.
Issue - Im getting a lot of voltage drop when battery is supplying power which is connected to the drain of MOSFET.
