17-V, 1.5-A, SYNCHRONOUS STEP-DOWN CONVERTER
High-Efficiency Synchronous Step-Down
The TPS6211x devices are a family of low-noise
Converter With up to 95% Efficiency
synchronous step-down dc-dc converters that are
ideally suited for systems powered from a 2-cell Li-ion
3.1-V to 17-V Operating Input Voltage Range
battery or from a 12-V or 15-V rail.
Adjustable Output Voltage Range From
The TPS6211x is a synchronous PWM converter with
1.2 V to 16 V
integrated
N-
and
P-channel
power
MOSFET
Fixed Output Voltage Options Available in
switches.
Synchronous
rectification
is
used
to
3.3 V and 5 V
increase efficiency and to reduce external component
Synchronizable to External Clock Signal up to
count. To achieve highest efficiency over a wide
1.4 MHz
load-current
range,
the
converter
enters
a
power-saving,
pulse-frequency
modulation
(PFM)
Up to 1.5-A Output Current
mode at light load currents. Operating frequency is
High Efficiency Over a Wide Load-Current
typically 1 MHz, allowing the use of small inductor
Range Due to PFM/PWM Operation Mode
and
capacitor
values.
The
device
can
be
100% Maximum Duty Cycle for Lowest
synchronized to an external clock signal in the range
Dropout
of 0.8 MHz to 1.4 MHz. For low-noise operation, the
converter can be operated in PWM-only mode. In the
20-A Quiescent Current (Typical)
shutdown mode, the current consumption is reduced
Overtemperature and Overcurrent Protected
to less than 2 A. The TPS6211x is available in the
Available in 16-Pin QFN Package
16-pin (RSA) QFN package, and operates over a
free-air temperature range of –40°C to 85°C.
Point-of-Load Regulation From 12-V Bus
