LTC3440 Datasheet - Linear Technology

LTC3440 Buck-Boost DC/DC Converter

The LTC®3440 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 operating modes, making the product ideal for single li.
