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.
