MAX77827 EVALUATION KIT AVAILABLE 5.5V Input, 1.8A/3.1A Switch Buck-Boost Converter with 6μA IQ General Description The MAX77827 is a high-efficiency buck-boost regulator targeted for one-cell Li-ion powered applications with the lowest typical quiescent current in the industry of 6μA. It supports input voltages of 1.8V to 5.5V and an output voltage range of 2.3V to 5.3V. The IC provides two different switching current levels (1.8A and 3.1A) to optimize external component sizing based on given load current requirements. With the 1.8A switching current-limit option, the IC can support up to 1.0A load current in buck mode and 900mA in boost mode (VIN = 3.0V, VOUT = 3.3V). The peak efficiency of 96% makes the IC one of the best solutions as a DC/DC converter to supply a rail for batterypowered portable applications. The IC features an adjustable output voltage, which can be programmed from 2.3V to 5.3V through a single resisto...
