AS3722 Multi-Phase DCDC Controller PMIC 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.
