The MP8845CG-Z is a highly integrated, high-frequency, synchronous, step-down switcher with an I2C control interface. The MP8845CG-Z can support up to 5A of load current over a 2.7V to 6V input supply range with excellent load and line regulation. Fixed-frequency hysteretic control mode provides an extremely fast transient response without loop compensation to achieve high efficiency easily under light-load conditions. The output 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 1.1V in 3.9mV steps. The voltage slew rate, switching frequency, and power-saving modes are also selectable through the I2C interface. Full protection features include internal soft start, over-current protection (OCP), and over-temperature protection (OTP). The MP8845CG-Z requires a minimum number of readily available, standard, external components and is available in a compact WLCSP-20 (1.70mmx2.10mm) package.
