EVQ28164-D-00A
High Efficiency Single Inductor
Buck-Boost DC-DC Converter
Evaluation Board
DESCRIPTION
FEATURES
The EVQ28164-D-00A Evaluation Board is
designed to demonstrate the capabilities of
MPS’ MPQ28164.
The MPQ28164 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 range.
The MPQ28164 operates with input voltage
from 1.2V to 5.5V to provide adjustable output
voltage (1.5V to 5V), and is available in QFN103x3mm package.
