MPQ8861 AEC-Q100 Synchronous Step-Down Converters

Monolithic Power Systems (MPS) MPQ8861 AEC-Q100 Synchronous Step-Down Converters are high-frequency, synchronous, rectified, step-down, switch-mode converters with an I²C control interface. The MPQ8861 devices offer a fully integrated solution that achieves 12A of continuous output current (I_OUT) with excellent load/line regulation across a wide input voltage (V_IN) supply range. The output voltage (V_OUT) level can be controlled on-the-fly via the I²C serial interface. The reference voltage (V_REF) range can be adjusted from 0.6V to 1.108V in 4mV steps. Functions such as voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable, and power-save mode are also selectable via the I²C.
