Qualified for Automotive Applications
synchronous step down current mode converter with
Two 12-m
(typical) MOSFETs for High
two integrated MOSFETs.
Efficiency at 4-A Loads
The TPS57114 -Q1 enables small designs by
200 kHz to 2 MHz Switching Frequency

the
MOSFETs,
implementing
current
0.8 V
± 1% Voltage Reference Over
mode control to reduce external component count,
Temperature (
–40°C to 150°C)
reducing inductor size by enabling up to 2 MHz
switching frequency, and minimizing the IC footprint
Synchronizes to External Clock
with a small 3 mm x 3 mm thermally enhanced QFN
Adjustable Slow Start/Sequencing
package.
UV and OV Power Good Output
The TPS57114 -Q1 provides accurate regulation for a
–40°C to 150°C Operating Junction
variety of loads with an accurate
±1% Voltage
Temperature Range
Reference (VREF) over temperature.
Thermally Enhanced 3mm
× 3mm 16-pin QFN
Efficiency is maximized through the integrated 12 m
Pin Compatible to TPS54418
MOSFETs and 515
μA typical supply current. Using
the enable pin, shutdown supply current is reduced to
APPLICATIONS
5.5
A by entering a shutdown mode.
Low-Voltage, High-Density Power Systems
Under voltage lockout is internally set at 2.45 V, but
Point of Load Regulation for High Performance
can be increased by programming the threshold with
a resistor network on the enable pin. The output
