850kHz 1A Buck DC/DC Converter
General Description
The AAT1152 SwitchReg is a step-down switching
converter ideal for applications where high efficien-
cy, small size, and low ripple are critical. Able to
deliver 1A with internal power MOSFETs, the cur-
rent mode controlled IC is internally compensated
for simplified system design and low external parts
count.
The AAT1152 features a Power-OK (POK) function
which monitors the output, alerting the system if
the output voltage falls out of regulation.
The AAT1152 is available in a Pb-free MSOP-8
package and is rated over the -40°C to +85°C tem-
perature range.
