MP8883

MPL Optimized Performance with MPS Inductor The MP8883 is a high-frequency, synchronous, rectified step-down converter with an I2C control interface and multiple-page one-time programmable (OTP) memory. It can achieve up to 3A of continuous output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation. The MP8883 is designed to be very versatile. The output voltage (VOUT) can be set between 0.8V and 12V via the I2C serial interface. The switching slew rate, switching frequency (fSW), enable (EN) control, and power-save mode can also be configured via the I2C. This allows users to optimize each output for the specific application requirements. During bench evaluations, different configurations can be evaluated via the I2C interface instead of reworking external components. The OTP can permanently store the optimal settings. The integrated, internal high-side and low-side power MOSFETs (HS-FETs and LS-FETs, respectively) provide high efficiency without the use of an external Schottky diode. Current mode provides fast transient response and eases loop stabilization. Full protection features include under-voltage lockout (UVLO) protection, over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown. With an internal feedback (FB) divider and compensation, the MP8883 offers a very compact solution with a minimal number of readily available, standard external components. It is available in a QFN-16 (3mmx3mm) package.
