BUCK SWITCHER SUPPLIES
and SW2 are used for supplying the application processor core power domains. Split power domains allow independent DVS
control for processor power optimization, or to support technologies with a mix of device types with different voltage ratings. SW3
is used for powering internal processor memory as well as low voltage peripheral devices and interfaces which can run at the
same voltage level. SW4 is used for powering external memory as well as low voltage peripheral devices and interfaces which
can run at the same voltage level.

Four buck switchers are provided with integrated power switches and synchronous rectification. In a typical application, SW1
An anticipated platform use case applies SW1 and SW2 to processor power domains that require voltage alignment to allow
The buck switchers have to be supplied from the system supply BP, which is drawn from the main battery or the battery charger
