3 Description

The TPS65010 device is an integrated power and

battery management IC for applications powered by

one Li-Ion or Li-Polymer cell, and which require

multiple power rails. The TPS65010 provides two

highly efficient, 1.25-MHz step-down converters

targeted at providing the core voltage and peripheral,

I/O rails in a processor-based system. Both stepdown

converters enter a low-power mode at light load

for maximum efficiency across the widest possible

range of load currents. The TPS65010 also integrates

two 200-mA LDO voltage regulators, which are

enabled through the serial interface. Each LDO

operates with an input voltage range from 1.8 V to

6.5 V, thus allowing them to be supplied from one of

the step-down converters or directly from the battery.

The TPS65010 also has a highly integrated and

flexible Li-Ion linear charger and system power

management. It offers integrated USB-port and ACLi-

adapter supply management with autonomous power-

source selection, power FET and current sensor, high

accuracy current and voltage regulation, charge

status, and charge termination.
