DESCRIPTION
The MP8847 is a highly integrated, highfrequency, synchronous, step-down switcher with an I2C control interface. The MP8847 can support up to 6A of load current over an input supply range from 2.7V to 6V with excellent load and line regulation.
Constant-frequency hysteretic mode provides an extremely fast transient response without loop compensation to achieve high efficiency easily under light-load condition. The output voltage level can be controlled onthe-fly through a 3.4Mbps I2C serial interface.
The voltage range can be adjusted from 0.6V to 1.235V in 5mV steps. The voltage slew rate, switching frequency, and power-saving mode are also selectable through the I2C interface.
Full protection features include internal soft start, over-current protection (OCP), and overtemperature protection (OTP).
The MP8847 requires a minimal number of readily available, standard, external components and is available in a compact QFN-14(2mmx3mm) package.
