Description

General part information

LTC3785 Series

The LTC3785 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.The operating frequency can be programmed from 100kHz to 1MHz. The soft-start time and current limit are also programmable. The soft-start capacitor doubles as the fault timer which can program the IC to latch off or recycle after a determined off time. Burst Mode operation is user controlled and can be enabled by driving the MODE pin high.Protection features include foldback current limit, shortcircuit and overvoltage protection.Power GoodLTC3785NoLTC3785-1YesApplicationsPalmtop ComputersHandheld InstrumentsWireless ModemsCellular Telephones
