Monolithic Power Systems MP2155 High Efficiency 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. 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. MP2155 provides power solutions for products powered by a one-cell Lithium-Ion or multi-cell alkaline battery applications where the output voltage is within battery voltage range. To ensure the longest battery life, MP2155 features an optional pulse skipping mode to reduce 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. These features make the MP2155 High Efficiency Single Inductor Buck-Boost Converters well-suited for battery-powered products, portable instruments, tablet PCs, POS systems, GSM/GPRS, and systems controls.
