AAT1151
850kHz 700mASynchronous Buck DC/DC Converter

General Description
The AAT1151 SwitchReg is a member of
AnalogicTech's Total Power Management IC
(TPMIC) product family. The step-down switching
converter is ideal for applications where high effi-
ciency is required over the full range of output load
conditions. The 2.7V to 5.5V input voltage range
makes the AAT1151 ideal for single-cell lithium-
ion/polymer battery applications. Capable of more
than 700mA with internal MOSFETs, the current-
mode controlled IC provides high efficiency using
synchronous rectification. Fully integrated compen-
sation simplifies system design and lowers external
parts count.
The device operates at a fixed 850kHz switching fre-
quency and enters PFM mode for light load current
to maintain high efficiency across all load conditions.
The AAT1151 is available in MSOP-8 and QFN33-16
packages and is rated over the -40°C to +85°C tem-
perature range.
