MP2155GQ-Z

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 range.

The MP2155 uses a current mode, fixed

frequency PWM control for optimal stability and

transient response. The fixed 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 MP2155 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 MP2155 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 1A current to load at

3.3V output voltage. The MP2155 is available in

small QFN10-3x3mm package
