製品概要

The MAX8967 evaluation kit (EV kit) is a fully assembled and tested PCB for evaluating the MAX8967, which is a µPMIC with two step-down switching converters and six LDOs. The step-down converters deliver up to 2A of output current independently. Two of the LDOs deliver a load current up to 300mA, while four of the LDOs deliver up to 150mA. Both step-down converters have remote sense, allowing accurate load regulation. The device operates over a 2.6V to 5.5V input supply range.
The IC supports dynamic adjustment of the output voltage through its I2C interface. Each step-down converter has two register settings for output voltage and a setting for ramp rate. Each step-down converter has a dedicated enable pin and a dedicated VID_ pin to toggle between the two programmed output voltages. Additionally, an interrupt output is provided, allowing the device to signal its master.
