SLVS607B – SEPTEMBER 2005 – REVISED JULY 2007
POWER MANAGEMENT IC FOR LI-ION POWERED SYSTEMS
1.2 A, 97% Efficient Step-Down Converter for
The TPS65020 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

rails. The TPS65020 provides three highly efficient,
for Memory Voltage (VDCDC2)
step-down converters targeted at providing the core

based
system.
All
three
step-down
20 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 TPS65020 also integrates two
2 × 200 mA LDO for SRAM and PLL
200-mA LDO voltage regulators, which are enabled

with an external input pin. Each LDO operates with
Core
an input voltage range between 1.5 V and 6.5 V,
allowing them to be supplied from one of the
Externally Adjustable Reset Delay Time
step-down converters or directly from the main

supply in a Intel PXA270 based system. The serial
interface is used for dynamic voltage scaling of the
