Wide VIN Triple Output 1A Buck-Boost and Dual 600mA Synchronous Buck Converters in 4x4 QFN
The LTC3521 combines a synchronous 1A buck-boost DC/DC converter with dual 600mA synchronous step-down DC/DC converters to offer three output rails with efficiencies as high as 95%. The LTC3521's input range of 1.8V to 5.5V makes it compatible with all types of PC card slots, USB and single-cell Li-Ion or dual/triple-cell alkaline/NiCd/NiMH applications. The topology incorporated in the LTC3521's synchronous buck-boost channel provides a continuo...
LTC3614 - 4A, 4MHz, Synchronous Step-Down Regulator in 3mm x 5mm QFN
The LTC3614 is a high efficiency synchronous buck regulator from Linear Technology that incorporates a constant frequency, current mode architecture capable of switching frequencies up to 4MHz. Low resistance internal switches allow the LTC3614 to deliver up to 4A of continuous output current from a 3mm x 5mm QFN package, and its low dropout operation allows the output voltage to range from 0.6V to just millivolts below VIN. The LTC3614 operates ...
