1 / 37 page  MP8869 17V, 12A, High-Efficiency, Synchronous Step-Down Converter with Integrated Telemetry via I 2C Interface MP8869 Rev.1.0 www.MonolithicPower.com 1 6/8/2016 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2016 MPS. All Rights Reserved. DESCRIPTION The MP8869 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I 2C control interface. It offers a fully integrated solution that achieves 12A of continuous and 15A of peak output current with excellent load and line regulation over a wide input supply range. In the I 2C control loop, the output voltage level can be controlled on-the-fly through an I 2C serial interface. The voltage range can be adjusted from 0.6V to 1.87V in 10mV steps. Voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable, and power saving mode are also selectable through the I 2C interface. Constant-on-time (COT) control operation provides fast transient response. An open-drain power good (PG) pin indicates that the output voltage is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown. The MP8869 is available in a QFN-14 (3mmx4mm) package. FEATURES Wide 4.5V to 17V Operating Input Range 12A Continuous/15A Peak Output Current 1% Internal Reference Accuracy I2C Programmable Output Range from 0.6V to 1.87V in 10mV Steps with Slew Rate Control 5% Accuracy Output Voltage and Output Current Readback via I 2C Selectable PFM/PWM Mode, Adjustable Frequency and Current Limit through I 2C 4 Different Selectable I2C Addresses External Soft Start Open-Drain Power Good Indication Output Over-Voltage Protection (OVP) Hiccup/Latch-Off OCP Available in a QFN-14 (3mmx4mm) Package APPLICATIONS Solid-State Drives (SSDs) Flat-Panel Television and Monitors Digital Set-Top Boxes Distributed Power Systems Networking/Servers All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
