2 Applications

• TPS63805

– System pre-regulator (smartphone, tablet, left

terminal, and telematics)

– Point-of-load regulation (wired sensor, port/

cable adapter, and dongle)

• TPS63806

– Time-of-flight camera sensor (smartphone,

electronic smart lock, and ip network camera)

• TPS63807

– Applications needing an output discharge

feature

3 Description

The TPS63805, TPS63806, and TPS63807 are high

efficiency, high output current buck-boost converters.

Depending on the input voltage, they automatically

operate in boost, buck, or in a novel 4-cycle buck-

boost mode when the input voltage is approximately

equal to the output voltage.
