MP28167GQ-Z

Monolithic Power Systems MP28163 High Efficiency Single Inductor Buck-Boost Converter with 2.9A Switches is a highly efficient, low quiescent current buck-boost converter designed to operate from an input voltage above, below, and equal to the output voltage. MP28163 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, MP28163 can supply a maximum 1.3A current to load at 3.3V output voltage. MP28163 provides a 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. To ensure the longest battery life, MP28163 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 and the small QFN10-3x3mm package make MP28163 well-suited for battery-powered products, portable instruments, tablet PCs, POS systems, and GSM/GPRS applications.
