MPQ8847A is a highly integrated, high frequency, high efficiency, synchronous step-down converter with an I2C control interface. The MPQ8847A can support up to 6A of load current across an input voltage (VIN) 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 under light-load conditions. The output voltage (VOUT) 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 VOUT slew rate, switching frequency (fSW), and power-save mode can be configured via the I2C interface. It is available in a compact QFN-14 (2.5mmx3mm) package. Applications include automotive infotainment systems, automotive telematics systems, advanced driver assistance systems (ADASs), automotive applications, processor core supplies.
