3 Description

The TPSM83102 and TPSM83103 are constant

frequency peak current mode control buck-boost

converters in samll μSiP module package. It has a

3A peak current limit (typical) and 1.6V to 5.5V input

voltage range, and provide a power supply solution for

system pre-regulators and voltage stabilizers.

Depending on the input voltage, the TPSM83102 and

TPSM83103 automatically operate in boost, buck, or

in 3-cycle buck-boost mode when the input voltage

is approximately equal to the output voltage. The

transitions between modes happen at a defined

duty cycle and avoid unwanted toggling within the

modes to reduce output voltage ripple. 8-μA quiescent

current and power save mode power enable the

highest efficiency for light to no-load conditions.

The device offers a very small solution size in μSiP

module package.
