FEATURES
APPLICATIONS
Portable and handheld systems
The purpose of the TPS65910 device is to
provide the following resources:
OMAP3 power management
Embedded power controller
DESCRIPTION
Two efficient step-down dc-dc converters for
processor cores
The TPS65910 is an integrated power-management
IC available in 48-QFN package and dedicated to
One efficient step-down dc-dc converter for I/O
applications powered by one Li-Ion or Li-Ion polymer

(internal purpose)
Two of the step-down converters provide power for
One high-speed I2C interface for
dual processor cores and are controllable by a
general-purpose control commands (CTL-I2C)
dedicated class-3 SmartReflex interface for optimum
