Analog Devices / Maxim Integrated MAX77816升降壓穩壓器

Maxim Integrated MAX77816升降壓穩壓器是一種定位於單節鋰電池驅動應用的高電流、高效率裝置。MAX77816支持2.60V至5.14V的寬輸出電壓範圍，允許5A（典型值）最高切換電流。

The Analog Devices MAX77816 Buck-Boost Regulators have an output current of up to 4A in buck mode and a maximum output current of up to 3A in boost mode. A unique control algorithm allows high efficiency, outstanding line/load transient response, and seamless transition between buck and boost modes.
