5.2.3 DC/DC Converter
The power supply for a handheld device should be able to keep the DC
voltage output at a constant level even though the input battery voltage
is continuously dropping down, so a 3.3 V DC/DC converter is designed
for the whole system, including the MCU and the baseband IC and RF
module.
