3 Description

The TPSM83100 and TPSM83101 are constant

frequency peak current mode control buck-boost

MicroSiP™ power modules optimized for small

solution size and high efficiency. The power modules

integrate an inductor to simplify design, reduce

external components and save PCB area. They

have a 3-A peak current limit (typical) and 1.6-V

to 5.5-V input voltage range. The TPSM83100 and

TPSM83101 provide a power supply solution for

system pre-regulators and voltage stabilizers.

Depending on the input voltage, the TPSM83100 and

TPSM83101 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 enable the highest

efficiency for light to no-load conditions.
