The TPS6507x are single chip Power Management
3 Step-Down Converters:
ICs for portable applications consisting of a battery
–
2.35MHz Fixed Frequency Operation
charger with power path management for a single
Li-Ion or Li-Polymer cell. The charger can either be
–
Up to 1.5A of Output Current
supplied by a USB port on pin USB or by a dc voltage
–
Adjustable or Fixed Output Voltage
from a wall adapter connected to pin AC. Three

using
the
I2C
interface.
The
–
100% Duty Cycle for Lowest Dropout
step-down converters allow the use of small inductors
LDOs:
and capacitors to achieve a small solution size. The
–
Fixed Output Voltage
TPS6507x also integrate two general purpose LDOs
for an output current of 200mA. These LDOs can be

used
to
power
an
SD-card
interface
and
an

20mA Quiescent Current
always-on rail, but can be used for other purposes as
–
200mA Maximum Output Current
well. Each LDO operates with an input voltage range
between 1.8V and 6.3V allowing them to be supplied
–
VIN Range From 1.8V to 6.3V
from one of the step-down converters or directly from
wLED Boost Converter:
the main battery. An inductive boost converter with

two programmable current sinks power two strings of
white LEDs.
–
Up to 2 × 10 LEDs
–
Up to 25mA per String With Internal Current
The TPS6507x come in a 48-pin leadless package
Sink
(6mm × 6mm QFN) with a 0.4mm pitch.
