Evaluation KitGET THIS KIT
The EV8846-Q-00A is used for demonstrating the performance of MPS’s MP8846. MP8846 is a highly integrated and high frequency synchronous step-down switcher with I2C control interface. It is optimized to support up to 6A load current over an input supply range from 4.5V to 8V with excellent load and line regulation.
Current-Mode operation provides fast transient response and eases loop stabilization. The reference voltage level can be controlled, on-the fly through a 3.4Mbps I2C serial interface. The voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. The voltage slew rate, switching frequency and power savings mode are also selectable through the I2C interface. Fully protection features includes over current protection, over voltage protection and over temperature protection.
MP8846 is available in QFN15 (3mmx3mm) package.
