LTC3522
Synchronous 400mA
Buck-Boost and 200mA
Buck Converters
FEATURES DESCRIPTION ■ The LTC®3522 combines a 400mA buck-boost DC/DC converter with a 200mA synchronous buck DC/DC converter in
a tiny 3mm × 3mm package. The 1MHz switching frequency
minimizes the solution footprint while maintaining high
efficiency. Both converters feature internal soft-start and
compensation, simplifying the design process. ■
