DESCRIPTION

The EV28164-D-00A Evaluation Board is

designed to demonstrate the capabilities of

MPS’ MP28164.

The

MP28164

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 MP28164 operates with input voltage from

1.2V to 5.5V to provide adjustable output

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

3x3mm package.

Note 1): This board can support 2A load if VIN>2.4V, the load

capability is lower when VIN<2.4V due to inductor peak current

limit.
