General Description
The BU9000xGWZ are a high efficiency 6MHz synchronous step-down switching regulator with ultra low current PFM mode.
It provides up to 1.0A load current and an input voltage range from 3.0V to 5.5V, optimized for battery powered portable applications.
BU9000xGWZ has a mode control pin that allows the user to select Forced PWM(Pulse Width Modulation)mode or PFM(Pulse Frequency Modulation) and PWM auto change mode utilized power save operation at light load current.


FEATUREs
◾ Fast transient response
◾ Automatic PFM/PWM operation
◾ Forced PWM operation
◾ Internal Soft Start
◾ Under voltage lockout
◾ Over current protection
◾ Thermal shutdown


APPLICATIONs
   Smart phones, Cell phones, Portable applications and
   Micro DC/DC modules, USB accessories
