LTC3785
10V, High Efficiency,
Synchronous, No RSENSE
Buck-Boost Controller
Description Features The LTC®3785 is a high power synchronous buck-boost
controller that drives all N-channel power MOSFETs from
input voltages above, below and equal to the output voltage. With an input range of 2.7V to 10V, the LTC3785 is
well suited for a wide variety of single or dual cell Li-Ion
or multicell alkaline/NiMH applications. Single Inductor Architecture Allows VIN Above,
Below or Equal to VOUT
