MP8861 Step-Down Converters w/Integrated Telemetry Monolithic Power Systems (MPS) MP8861 Step-Down Converters with Integrated Telemetry offer a fully integrated solution that achieves 6A of continuous output current with superior load/line regulation over a wide input supply range. The I2C interface adjusts the reference voltage range from 0.6V to 1.108V in 4mV steps. Additionally, the output voltage level, voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable, and power-save mode (PSM) are also selectable through the I2C interface.
