MP2155

High Efficiency

Single Inductor Buck-Boost Converter

with 2.2A Switches

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

High Efficiency up to 95%.

Load Disconnect During Shutdown

Input Voltage Range: 2V to 5.5V

Adjustable Output Voltage from 1.5V to 5V

3.3V/1A Load Capability from 2.7V-to-5.5V

Vin

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.

•

1MHz Switching Frequency

Pulse Skipping Mode at Light Load

Typical 80μA Quiescent Current

Internal Loop Compensation for Fast

Response

The MP2155 uses a current mode, fixed

frequency PWM control for optimal stability and

transient response. The fixed 1MHz switching

frequency and integrated low R_DS(ON)N-channel

and P-channel MOSFETs minimize the solution

footprint while maintaining high efficiency.

Internal Soft Start

OTP, Hiccup SCP

Available in Small 3x3mm QFN10 Package

APPLICATIONS

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.

System Controls

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Quality Assurance.

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.
