MP8847 Synchronous Step-Down Converter

Monolithic Power Systems (MPS) MP8847 Synchronous Step-Down Converter is a highly integrated, high-frequency, step-down switcher with an I²C control interface. The MP8847 supports up to 6A load current over a 2.7V to 6V input supply range with excellent load/line regulation. Constant-frequency hysteretic mode provides a swift 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 1.235V 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 over-temperature protection (OTP). The MP8847 requires a minimal number of readily available, standard external components and is available in a compact QFN-14 (2mm x 3mm) package.
