MP8868 High-Efficiency, 10A, 17V, Synchronous 2 Step-Down Converter with I C Interface The Future of Analog IC Technology DESCRIPTION FEATURES The MP8868 is a high-frequency, synchronous, Wide 4.5V-to-17V Operating Input Range rectified, stepdown, switch-mode converter with 1% Internal Reference Accuracy 2 an I2C control interface. Its fully integrated IC Programmable Reference Output solution achieves a 10A output current with Voltage excellent load and line regulation over a wide Range from 0.6V to 1.87V in 10mV Steps input-supply range. with Slew Rate Control 2 I C Selectable Switching Frequency The reference voltage level is controlled on-the- 2 200kHz-2MHz Synchronized External Clock fly by the I C serial interface with the reference OTP, OCP Hiccup Indication Via I2C voltage range adjustable from 0.6V to 1.87V in 10mV steps. In addition, the voltage scaling Selectable PSM and Fs Through I2C slew rate, the switching frequency, enable, and Programmable Soft-Start Time power-save mode are selectable through the Open-Drain Power Good Indicator I2C interface. Small 3x4mm QFN14 Package Current-mode operation provides fast transient APPLICATIONS response and eases loop stabilization. SoC and Media Processors EN/SYNC supports external clock FPGA-based Systems synchronization, and an open-drain power good ASIC Supplies pin indicates when the output voltage is in the Distributed Power Systems nominal range. Full protection features include: All MPS parts are lead-free, halogen free, and adhere to the RoHS Over-voltage protection (OVP) directive.
