Laptop power system architecture -NB power system introduction

As we know, notebook power is provided by adaptors (19V) or batteries (14.8V ) however, the various power voltages do not fit all devices in a notebook unit. So a series of voltage transfer actions are needed to provide power to all devices. (Problems may arise during the voltage transfer.)

As notebook is a portable computer, saving power is also very important when the system is in battery mode. In this lesson, we will use the Yuhina power circuit to introduce the notebook power system.
