PMIC Datasheet
Confidential A
MT6333 is available in a WLCSP - 30L package.
The operating temperature ranges from -20 to
+80°C.
1.2 Applications
For power management of smart phones and
other portable systems.
1.3 General Descriptions
MT6333 is a sub-power management system
chip optimized for 2G/3G handsets and smart
phones, especially based on the MediaTek
MT6323/MT6322 system solution.
MT6333 highly integrates one boost converter
for flashlight driver and 3 buck converters for
system power optimization.
The boost mode can be used to supply
flashlight from VLED pin.
MT6333 also integrates three buck converters
for VCORE/VMEM/VRF which is used for
higher current demand.
Buck_En pin is provided for power-on sequence
controlled by main PMIC, and Sleep_B pin is for
sleep mode control.
