Datasheet Summary
LTC3444 Micropower Synchronous Buck-Boost DC/DC Converter for WCDMA Applications DESCRIPTIO
The LTC®3444 is a highly efficient, fixed frequency, buckboost DC/DC converter, which operates from input voltages above, below, and 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 a single Lithium-Ion or multi-cell applications where the output voltage can vary over a wide range. The LTC3444 has been optimized for use in 3G WCDMA applications. A unique design yields high efficiency at very low output voltages while also eliminating external ponents. The high speed error amplifier...
