Analog Devices / Maxim Integrated MAX77816 Buck-Boost Regulator

Analog Devices MAX77816 Buck-Boost Regulator is a high-current, high-efficiency device targeting single-cell Li-ion battery-powered applications. The MAX77816 supports a wide 2.60V to 5.14V output voltage range and allows a 5A (typical) maximum switch current.

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.
