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. The device

has 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 power enable the

highest efficiency for light to no-load conditions.
