MP8864
DESCRIPTION
The MP8864 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. It offers a very pact solution to achieve a 4 A continuous output current with excellent load and line regulation over a wide input supply range. The MP8864 has synchronous-mode operation for higher efficiency over the output load range.
The reference voltage level is controlled, on-the-fly through a 3.4 Mbps I2C serial interface. The voltage range can be adjusted from 0.6 V to 1.87 V in 10 m V steps. Also, the voltage slew rate, switching frequency, enable, and power-saving mode are selectable through the I2C interface.
Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown (TSD).
The MP8864 requires a minimal number of readily available, standard external ponents and is available in a 15-pin QFN15 (3mm x 3mm)...
