DESCRIPTION
• 3 Step-Down Converters:
The TPS6507x are single chip Power Management
– 2.25MHz Fixed Frequency Operation
ICs for portable applications consisting of a battery
charger with power path management for a single Li-
– Up to 1.5A of Output Current
Ion or Li-Polymer cell. The charger can either be
– Adjustable or Fixed Output Voltage
supplied by a USB port on pin USB or by a dc voltage
– V
IN
Range From 2.8V to 6.3V
from a wall adapter connected to pin AC. Three
– Power Save Mode at Light Load Current
highly efficient 2.25MHz step-down converters are
targeted at providing the core voltage, memory and
– Output Voltage Accuracy in PWM Mode
I/O voltage in a processor based system. The step-
±1.5%
down converters enter a low power mode at light load
– Typical 19 μA Quiescent Current per
for maximum efficiency across the widest possible
Converter
range of load currents. For low noise applications the
devices can be forced into fixed frequency PWM
– 100% Duty Cycle for Lowest Dropout
using the I

C interface. The step-down converters
• LDOs:
allow the use of small inductors and capacitors to
– Fixed Output Voltage
achieve a small solution size. The TPS6507x also
integrate two general purpose LDOs for an output
– Dynamic Voltage Scaling on LDO2
current of 200mA. These LDOs can be used to power
– 20μA Quiescent Current
an SD-card interface and an always-on rail, but can
– 200mA Maximum Output Current
be used for other purposes as well. Each LDO
– V
IN
Range From 1.8V to 6.3V
operates with an input voltage range between 1.8V
and 6.3V allowing them to be supplied from one of
• wLED Boost Converter:
the step-down converters or directly from the main
– Internal Dimming Using I2C
battery. An inductive boost converter with two
– Up to 2 × 10 LEDs
programmable current sinks power two strings of
white LEDs.
– Up to 25mA per String With Internal Current
Sink
The TPS6507x come in a 48-pin leadless package
(6mm × 6mm QFN) with a 0.4mm pitch.
