A Power management section in mobile phones is designed to handle
energy matters that is consumed by mobile phones. There are two main
subsections in a phone power system.
1. The power distribution and switching section
2. Charging section
A power distribution section is designed to distribute desired voltages
and currents to the other sections of the phone. This section takes
power from the battery( which is commonly 3.6V) and converts or steps it down to various volts like 2.8V, 1.8V, 1.6V, etc.
While another steps it up the voltage to like 4.8V. This
section is commonly designed around a power IC (Integrated Circuit)
which is used to distribute and regulate the voltage used in other
components.
It gladdens my heart when ever am permitted to share the
surface, faint and minute knowledge that have about ICT with the rest of the
world. Please endeavor to leave a comment below after reading this post.
