Work in progress!
Allow systems to dynamically control regulator power output in order to save power and prolong battery life.
Voltage Regulators take an input supply and produce a target voltage.
Which devices need Regulators?
Audio
WiFi
BT
HDMI etc.
Why do we need to drive the regulator?
Power saving
Hardware Interfacing
Which Devices need a dynamic regulator?
SD Card | Requires two supplies. 1.8v and 3.3v But no need to change dynamically voltage. | |
Types of Regulator
PMIC
GPIO Regulator
SoC built-in regulator
