FEATURES
DESCRIPTION
The purpose of the TPS65910 device is to
provide the following resources:
The TPS65910 is an integrated power-management
IC available in 48-QFN package and dedicated to
Embedded power controller
applications powered by one Li-Ion or Li-Ion polymer
Two efficient step-down dc-dc converters for
battery cell or 3-series Ni-MH cells, or by a 5-V input;
processor cores
it requires multiple power rails. The device provides
One efficient step-down dc-dc converter for I/O
three step-down converters, one step-up converter,
power
and eight LDOs and is designed to support the

OMAP-based
applications.
SmartReflex
compliant dynamic voltage
management for processor cores
Two of the step-down converters provide power for
8 LDO voltage regulators and one RTC LDO
dual processor cores and are controllable by a
(internal purpose)
dedicated class-3 SmartReflex interface for optimum
power savings. The third converter provides power for
One high-speed I2C interface for
the I/Os and memory in the system.
general-purpose control commands (CTL-I2C)
One high-speed I2C interface for SmartReflex
The device includes eight general-purpose LDOs
