General Description
The AS3722 is a compact System PMU supporting up to 20 high
current rails.
The device offers advanced power management functions. All
necessary ICs and peripherals in a battery powered mobile
device are supplied by the AS3722. It features 4 DCDC buck
converters as well as 11 low noise LDOs. The different regulated
supply voltages are programmable via the serial control
interface. 3-4MHz operation with 0.47uH coils is reducing cost
and PCB space.
AS3722 further features 3 DCDC buck controller which are ideal
to support processor currents ranging from 5A up to 32A
depending on the used power stages. The multi-phase
topology operating on 3MHz ensures fast load transient
responses and reduces the footprint for external components.
The single supply voltage may vary from 2.7V to 5.5V.
