3 Description

The TPS63802 is a high efficiency, high output

current buck-boost converter. It is used when the

input voltage is higher, equal, or lower than the output

voltage. Output currents up to 2 A are supported over

a wide voltage range. The device limits the peak

current at 4.5 A in Boost-Mode and 3.5 A in Buck-

Mode. The device is adjusted to the programmed

output voltage. It automatically changes from buck to

boost operation based on the input voltage. It

remains in a 3-cycle buck-boost mode when the input

voltage is approximately equal to the output voltage.

The

transitions

happen

seamlessly

and

avoids

unwanted toggling within the modes. The TPS63802

comes in a 2 mm x 3 mm package. The device works

with tiny passive components to keep the overall

solution size small.
