Hello,
I'm doing BLE usb doungle product.I want to use the WB55RGV6 in low power mode. The system will be able to operate on battery. I have some questions about product development. Questions on below.
1) Can the product operate at 1.8V in low power mode?
2) I use lipo battery. My battery voltage range will be 3.5V-4.2V. VDDA can be minimum 1.62V. In this case, I need to scale the voltage between 1.65-1.8V. I cannot use a direct voltage divider for low power mode because the resistors will draw current. How can I build a circuit structure?
3) In what situations can I use SMPS?
