Analog Devices Inc. LTM4693 2A Buck Boost µModule® DC-DC Converter
Analog Devices LTM4693 2A Buck-Boost µModule® DC-DC Converter operates from input voltages above, below, or equal to the output voltage. The switching controller, power MOSFETs, inductor, and support components are included in the package. The advanced topology of the LTM4693 provides a continuous transfer through all operating modes. VIN operation from 2.6V to 5.5V covers a wide variety of power sources, including typical 3.3V and 5V. Output voltage ranging from 1.8V to 5.5V is set by an external resistor. Only a few external components are needed for a typical application.
The Analog Devices LTM4693 DC-DC Converter is offered in an ultrathin 3.5mm × 4.0mm × 1.25mm LGA package and is Pb-free and RoHS compliant.
