General Description
The AAT1154 SwitchReg is a member of
AnalogicTech's Total Power Management IC
product family. The Step-down switching converter
is ideal for applications where high efficiency, small
size, and low ripple are critical. Able to deliver 3A
with an internal power MOSFET, the current-mode
controlled IC provides high efficiency. Fully inter-
nally compensated, the AAT1154 simplifies system
design and lowers external part count.
The AAT1154 is available in an SOP-8 package,
rated over -40 to 85°C.
