1MHz 3A Step-Down DC/DC Converter
General Description
The AAT1154 SwitchReg is a step-down switching
converter ideal for applications where high efficien-
cy, small size, and low ripple are critical. Able to
deliver 3A with an internal power MOSFET, the cur-
rent-mode controlled IC provides high efficiency.
Fully internally compensated, the AAT1154 simpli-
fies system design and lowers external parts count.
The AAT1154 is available in a Pb-free SOP-8 pack-
age and is rated over the -40°C to +85°C tempera-
ture range.
