MAX77801 - High-Efficiency Buck-Boost Regulator - DC-DC开关调节器 - 2A High-Efficiency Buck and Boost Operating Including Seamless Transition Between Buck and Boost Mode - 美信半导体


The MAX77801 is a high-current, high-efficiency buck-boost targeted to mobile applications that use a Li-ion battery or similar chemistries. The MAX77801 utilizes a four-switch H-bridge configuration to support buck and boost operating modes. Buck-boost provides 2.60V to 4.1875V of output voltage range and up to 2A output current.

A unique control algorithm allows high efficiency, outstanding performances in line/load transient response, and seamless transition between buck and boost modes.

DVS (dynamic voltage scaling) input allows the host processor to switch between two preprogrammed output voltages. This feature minimizes power loss for given load conditions. The ramp-up and ramp-down slew rates are programmable through I²C.

The MAX77801 features I²C-compatible, 2-wire serial interface consisting of a bidirectional serial-data line (SDA) and a serial-clock line (SCL). It supports SCL clock rates up to 3.4MHz.
