MP2155 Single Inductor Buck-Boost Converters

Monolithic Power Systems MP2155 High Efficiency Single Inductor Buck-Boost Converters with 2.2A Switches are highly efficient, low quiescent current buck-boost converters designed to operate from an input voltage above, below, and equal to the output voltage. MP2155 offers an input voltage from 2V to 5.5V to achieve an adjustable output voltage (1.5V to 5V). With an input from 2.7V to 5.5V, MP2155 can supply a maximum 1A current to load at 3.3V output voltage.
