Hello, as I mentioned in the title, I'm designing a battery-powered UHF RFID reader. This is a challenging project for me; I'm pushing the limits.
MCU: stm32wb52cg
UHF RFID: ST25RU3993
Battery: li-ion (18650)
I'm using the ZigBee feature of the MCU. My question is, I need a design that's compatible with both batteries and works at 2.5V levels. Therefore, what kind of power circuit should I create? If I install a 4.2V battery, I need to use a step-down converter. If I use li-ion (18650), I need to use a booster. What do you think I should do?
2-Is a switching regulator used in a UHF RFID circuit?
3- I need to make a booster with the li socl2 battery. When the battery drops to 2v, should I make a step up for RFID reading performance?
