800mA, Synchronous Buck-Boost DC/DC Converter Offers Extended Battery Run Time for Li-Ion Powered Handhelds
The LTC3538 includes two N-Channel MOSFETs and two P-Channel MOSFETs (0.17 Ohm and 0.20 Ohm, respectively) to deliver efficiencies of up to 96%. Burst Mode® operation requires only 35uA of quiescent current while shutdown current is less than 1uA to further extend battery run-time. Other features include soft-start, current limiting, thermal shutdown and output disconnect in shutdown.
LTC3538EDCB is available from stock in a 2mm x 3mm 8-lead DFN package.
