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 QFN103x3mm 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.

QUICK START GUIDE
1.
Preset the load to some value, e.g. 0.5A, notice that the MP28164 may enter SCP hiccup if starting
up with a heavier load due to the startup current limit which is for inrush protection..
2.
Connect the positive and negative terminals of the load to the VOUT and GND pins, respectively.
3.
Preset the power supply’s output voltage (1.8~5.5V), and then turn off the power supply.
4.
Connect the positive and negative terminals of the power supply output to the VIN and GND pins,
respectively.
5.
Turn on the power supply. The MP28164 demo board will automatically start up.
6.
To use the Enable function, apply a digital input to the EN pin. Drive EN higher than 1.2V to turn on
the regulator or less than 0.4V to turn it off.
7.
To use MODE pin for forced CCM operation, please turn off Vin then connect the jumper JP1 to
VIN.
8.
If other output voltage is preferred, The output voltage VOUT can be programmed by changing R1
and R2 according to below equation:
R2 = R1×
VFB
VOUT − VFB
Where VFB . Is typically 0.5V, and R1, R2’s units are in kΩ, VOUT ‘s unit is in V. The value of R1 is
recommended to be from 300 kΩ through 620 kΩ for better efficiency at light load. The
recommended output voltage can be from 1.5V through 5V.
