The LTC3785-1 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 LTC3785-1 is well suited for a wide variety of single or dual cell Li-Ion or multi-cell 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. The LTC3785-1 includes a Power Good output that indicates when the output voltage is within 7.5% of its designed setpoint. Protection features include foldback current limit, short-circuit and overvoltage protection.
