KB3440 converter equivalent, micropower synchronous buck-boost dc/dc converter.
include a 1µA shutdown, soft-start control, thermal shutdown and current limit. The kB3440 is available in the 10-pin thermally enhanced MSOP and (3mm × 3mm) DFN packages.
where the output voltage is within the battery voltage range. The device includes two 0.191 N-channel MOSFET switches an.
The kB3440 is a high efficiency, fixed frequency, BuckBoost DC/DC converter that operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides a continuous transfer function through all operati.
