AAT1162
12V, 1.5A Step-Down DC/DC Converter
General Description
Features
SwitchReg™
The AAT1162 is an 800kHz high efficiency step-
down DC/DC converter. With a wide input voltage
range of 4.0V to 13.2V, the AAT1162 is an ideal
choice for dual-cell Lithium-ion battery-powered
devices and mid-power-range regulated 12V-pow-
ered industrial applications. The internal power
switches are capable of delivering up to 1.5A to the
load.
The AAT1162 is a highly integrated device, simpli-
fying system-level design. Minimum external com-
ponents are required for the converter.
The AAT1162 optimizes efficiency throughout the
entire load range. It operates in a combination
PWM/Light Load mode for improved light-load effi-
ciency. The high switching frequency allows the use
of small external components. The low current shut-
down feature disconnects the load from VIN and
drops shutdown current to less than 1µA.
The AAT1162 is available in a Pb-free, space-sav-
ing, thermally-enhanced 16-pin TDFN34 package-
and is rated over an operating temperature range
of -40°C to +85°C.
