製品説明

The EV8864-Q-00A is used for demonstrating the performance of MPS’s MP8864. MP8864 is a highly integrated and high frequency synchronous step-down switcher with I2C control interface. It is optimized to support up to 4A load current over an input supply range from 4.5V to 21V with excellent load and line regulation.

Current-Mode operation provides fast transient response and eases loop stabilization. The output voltage level can be controlled, on-the fly through a 3.4Mbps I2C serial interface. Voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. Voltage slew rate, switching frequency and power savings mode are also selectable through the I2C interface. Fully protection features includes over current protection, over voltage protection and over temperature protection.

MP8864 is available in QFN15 (3mmx3mm) package.

6A, 6V, High-Efficiency, Synchronous, Step-Down Switcher with I2C Interface

The MP8848 is a highly integrated, high-frequency, synchronous, step-down switcher with an I2C control interface. The MP8848 can support up to 6A of load current over an input 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 easily under light-load condition. The output voltage level 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 voltage slew rate, switching frequency, and power-saving mode are also selectable through the I2C interface. Full protection features include internal soft start, over-current protection (OCP), and over-temperature protection (OTP). The MP8848 requires a minimal number of readily available, standard, external components and is available in a compact QFN-15 (2mmx3mm) package.
