Monolithic Power Systems MP8843

Description

The EV8843-G-00A is used for demonstrating the performance of MP8843, a highly integrated, high frequency, synchronous, step-down switcher with I2C control interface. MP8843 supports up to 3A current from a wide input supply range of 2.5V to 6V with excellent load and line regulation. Constant-on-time (COT) control provides fast transient response, high light-load efficiency and easy loop stabilization. The I2C interface allows for communication interface speed up to 3.4Mbps. It controls the output voltage on the fly from 0.6V to 1.1V with 3.9mV voltage steps and it also controls the output voltage transition slew rate. The interface also allows for the selection of power-save mode to meet different application requirements. Protection features include internal soft-start, over-current protection, and over-temperature protection. MP8843 is available in 2mmx2mm 12-pin QFN package
