General Description
The AAT1155 SwitchReg is a step-down switching
converter ideal for applications where high efficien-
cy, small size, and low ripple are critical. Able to
deliver 2.5A with an internal power MOSFET, the
current-mode controlled IC provides high efficien-
cy. Fully internally compensated, the AAT1155 sim-
plifies system design and lowers external parts
count.
The AAT1155 is available in a Pb-free MSOP-8
package and is rated over the -40°C to +85°C tem-
perature range.
