Step-Down Converter for Memory Voltage
Digital Still Camera
(VDCDC2)
Split Supply DSP and P Solutions:, Samsung
–
1.8V or 2.5V or Adjustable
ARM-Based Processors, etc.
0.8A, 90% Efficient Step-Down Converter for
Processor Core (VDCDC3)
Two Selectable Voltages for VDCDC3
The TPS65024x are integrated Power Management
–
TPS650240:
ICs for applications powered by one Li-Ion or
–
DEFDCDC3= LOW: VO = 1.0V
Li-Polymer cell, which require multiple power rails.
The
TPS65024x
provide
three
highly
efficient,
–
DEFDCDC3= HIGH: VO = 1.3V
step-down converters targeted at providing the core
–
TPS650241:
voltage, peripheral, I/O and memory rails in a
–
DEFDCDC3= LOW: VO = 0.9V
processor
based
system.
All
three
step-down
converters enter a low power mode at light load for
–
DEFDCDC3= HIGH: VO= 1.375V
maximum efficiency across the widest possible range
–
TPS650242:
of load currents. The converters can be forced into
–
DEFDCDC3= LOW: VO = 1.0V
fixed frequency PWM mode by pulling the MODE pin
–
DEFDCDC3= HIGH: VO = 1.5V
high. The TPS65024x also integrate two general
purpose 200mA LDO voltage regulators, which are
–
TPS650243:
enabled with an external input pin. Each LDO
–
DEFDCDC3= LOW: VO = 1.0V
operates with an input voltage range between 1.5V
–
DEFDCDC3= HIGH: VO = 1.2V
and 6.5V allowing them to be supplied from one of
the step-down converters or directly from the battery.
–
TPS650244:
The output voltage of the LDOs can be set with an
–
DEFDCDC3= LOW: VO = 1.55V
external
resistor
divider
for
maximum
flexibility.
–
DEFDCDC3= HIGH: VO = 1.6V
Additionally there is a 30mA LDO typically used to
provide power in a processor based system to a
–
TPS650245:
voltage rail that is always on. TPS65024x provide
–
DEFDCDC3= LOW: VO = 0.9V
voltage scaling on DCDC3 using the DEFDCDC3 pin.
–
DEFDCDC3= HIGH: VO = 1.1V
This pin either needs to be connected to a logic HIGH
or logic LOW level to set the output voltage of
30mA LDO for Vdd_alive
DCDC3. TPS65024x come in a small 5mm x 5mm 32
2 × 200mA General Purpose LDOs (LDO1 and
pin QFN package (RHB).
