DESCRIPTION
The TPS65020 is an integrated Power Management
IC
for
applications
powered
Li-Polymer cell, and which require multiple power
rails. The TPS65020 provides three highly efficient,
step-down converters targeted at providing the core
voltage, peripheral, I/O and memory rails in a pro-
cessor based system. All three step-down converters
enter a low-power mode at light load for maximum
efficiency across the widest possible range of load
currents. The TPS65020 also integrates two 50 mA
LDO voltage regulators, which are enabled with an
external input pin. Each LDO operates with an input
voltage range between 1.5 V and 6.5 V, allowing
them to be supplied from one of the step-down
converters or directly from the main battery. The two
50-mA LDO voltage regulators are intended for use
with the SDRAM and PLL power supply in a Intel
PXA270 based system. The serial interface is used
for dynamic voltage scaling of the core voltage,
masking interrupts, or for dis/enabling and setting the
LDO output voltages. The interface is compatible with
the Fast/Standard mode I
2
C specification, allowing
transfers at up to 400 kHz.
