Description

General part information

MAX77831 Series

The MAX77831 is a high-efficiency, high-performance buck-boost converter targeted for systems requiring wide input voltage range (2.5V to 16V). It features a 7A switching current and can supply up to 6A output current in buck mode and up to 4A in boost mode (boost ratio ≤ 1.3).The IC is available in 5V default output voltage when using internal feedback resistors. The IC can also be configured to any default output voltages between 3V and 15V when using external feedback resistors. The output voltage is adjustable dynamically through the I2C serial interface (see the Output Voltage Configuration section). The IC only operates in forced-PWM (FPWM) mode.The SEL pin allows a single external resistor to program four different I2C interface slave addresses, four different switching-current limit thresholds, and selection between external/internal feedback resistors. The different switching-current limit thresholds allow the use of lower profile and smaller external components that are optimized for a particular application. The use of external feedback resistors allows for a wider output voltage range and customizable output voltages at startup.The I2C serial interface is optional and allows dynamically controlling the output voltage, the slew rate of the output voltage change, switching-current limit threshold, and switching frequency. The I2C-programmed settings have priority over the RSELdecoded settings.The MAX77831 is available in a 2.83mm x 2.03mm 35-bump wafer level package (WLP).ApplicationsNon-Battery Powered Applications up to 16V InputBattery Powered Applications up to 16V Input with EN Control
