Packages

The LTC

3531/LTC3531-3.3/LTC3531-3 are synchronous

buck-boost DC/DC converters that operate from input

voltages above, below or equal to the output voltage. The

topology incorporated in the ICs provides a continuous

transfer through all operating modes, making the product

ideal for single cell Li-Ion and multicell alkaline or nickel

applications. The converters operate in Burst Mode, mini-

mizing solution footprint and component count as well as

providing high conversion efﬁciency over a wide range of

load currents.

The devices include two 0.5Ω N-channel MOSFET switches

and two P-channel switches (0.5Ω, 0.8Ω). Quiescent

current is typically 16μA, making the parts ideal for bat-

tery power applications. Other features include a <1μA

shutdown current, current limiting, thermal shutdown

and output disconnect. The parts are offered in a 6-pin

ThinSOT

package for ﬁxed voltage versions or a 3mm

3mm DFN package for ﬁxed and adjustable versions.
