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.

The EV2155-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP2155, a highly efficient, low quiescent current (IQ), buck-boost converter. It can operate from an input voltage (VIN) above, below, or equal to its output voltage (VOUT). The device is ideal for products powered by a single-cell lithium-ion or multi-cell alkaline battery where the IC’s VOUT is within the battery voltage range.
The device operates from a 2V to 5.5V VIN range, and has an adjustable 1.5V to 5V VOUT.
The MP2155 and is available in a QFN-10 (3mmx3mm) package.
