DESCRIPTION

The

EV2155-Q-00A

Evaluation

Board

is

designed to demonstrate the capabilities of

MPS’ MP2155.

The MP2155 is a highly efficient, low quiescent

current Buck-Boost converter, which operates

from input voltage above, below and equal to

the output voltage. The device provides power

solution for products powered by a one-cell

Lithium-Ion

or

multi-cell

alkaline

battery

applications where the output voltage is within

battery voltage rang.

The MP2155 operates with input voltage from

2V to 5.5V to provide adjustable output voltage

(1.5V to 5V), and is available in QFN10-3x3mm

package.
