Single Inductor Buck-Boost Converter

DESCRIPTION
The MP28163 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 MP28163 uses a current mode, fixed
frequency PWM control for optimal stability and
transient response. The fixed 1.1MHz switching
frequency and integrated low RDS(ON) N-channel
and P-channel MOSFETs minimize the solution
footprint while maintaining high efficiency.
To ensure the longest battery life MP28163 has
an optional pulse skipping mode that reduces
switching frequency under light load conditions.
For other low noise applications where variable
frequency power save mode may cause
interference, the logic control input MODE pin
forces fixed frequency PWM operation under all
load conditions.
The MP28163 operates with input voltage from
2V to 5.5V to provide adjustable output voltage
(1.5V to 5V). With an input from 2.7V to 5.5V, it
can supply a maximum 1.3A current to load at
3.3V output voltage. The MP28163 is available
in small QFN10-3x3mm package.
