DESCRIPTION
APPLICATIONS
SLVS667 – JULY 2006
POWER MANAGEMENT IC FOR LI-ION POWERED SYSTEMS
1.2 A, 97% Efficient Step-Down Converter for
The TPS65022 is an integrated Power Management
System Voltage (VDCDC1)
IC for applications powered by one Li-Ion or
Li-Polymer cell, and which require multiple power
1 A, Up to 95% Efficient Step-Down Converter
rails. The TPS65022 provides three highly efficient,
for Memory Voltage (VDCDC2)
step-down converters targeted at providing the core
900 mA, 90% Efficient Step-Down Converter
voltage, peripheral, I/O and memory rails in a
for Processor Core (VDCDC3)
processor
based
system.
All
three
step-down
30 mA LDO/Switch for Real Time Clock
converters enter a low-power mode at light load for
maximum efficiency across the widest possible range
(VRTC)
of load currents. The TPS65022 also integrates two
2 x 200 mA General-Purpose LDO
general-purpose 200 mA LDO voltage regulators,
Dynamic Voltage Management for Processor
which are enabled with an external input pin. Each
Core
LDO operates with an input voltage range between
1.5 V and 6.5 V, allowing them to be supplied from
Preselectable LDO Voltage Using Two Digital
one of the step-down converters or directly from the
Input Pins
battery. The default output voltage of the LDOs can
