MAX77839 Highly-Efficient Buck-Boost Regulators

Analog Devices MAX77839 Highly-Efficient Buck-Boost Regulators feature an industry-leading quiescent current of 6μA. The devices are targeted for a one-cell Li-ion and down to any battery chemistry with 1.8V discharge voltage. 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 limits to optimize external component sizing based on the given load current requirements. The Analog Devices MAX77839 Buck-Boost Regulator is available in a 2.07mm x 1.51mm, 15-bump Wafer-Level Package (WLP) and in a 2.5mm x 2.0mm, 11-lead FC2QFN package.
