The EVL8853-Q-00A is an evaluation board designed to demonstrate the capabilities of the MP8853, a high-efficiency, synchronous, step-down converter with an I²C interface.

The MP8853 is a high-frequency, synchronous rectified, step-down, switch-mode converter with an I²C interface. The MP8853 offers a fully integrated solution that achieves up to 4A of continuous output current (I_OUT), with excellent load and line regulation across a wide input supply voltage (V_IN) range. The output voltage (V_OUT) can be controlled on the fly via the I²C interface. The reference voltage (V_REF) can be adjusted from 0.6V to 1.108V in 4mV steps. The voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable, and power-save mode (PSM) are also selectable via the I²C interface.

Constant-on-time (COT) control operation provides fast transient response. An open-drain power good (PG) pin indicates whether V_OUT is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown.

It is recommended to read the datasheet for the MP8853 prior to making any changes to the EVL8853-Q-00A.
