1 / 39 page  MP8869S 18V, 12A, High-Efficiency, Wide-Input, Synchronous, Step-Down Converter with Integrated Telemetry via I2C Interface MP8869S Rev. 1.03 www.MonolithicPower.com 1 1/18/2018 MPS Proprietary Information. Patent Protected. Unauthorized Photocopy and Duplication Prohibited. © 2018 MPS. All Rights Reserved. DESCRIPTION The MP8869S is a high-frequency, synchronous, rectified, step-down, switch-mode converter with an I2C control interface. The MP8869S offers a fully integrated solution that achieves 12A of continuous current and 15A of peak output current with excellent load and line regulation over a wide input supply range. The output voltage level can be controlled on- the-fly through an I2C serial interface. The reference voltage range can be adjusted from 0.6V to 1.108V in 4mV steps. The voltage slew rate, frequency, current limit, hiccup/latch-off protection, enable, and power-saving mode are also selectable through the I2C interface. Constant-on-time (COT) control operation provides fast transient response. An open-drain power good (PG) pin indicates when the output voltage is in the nominal range. Full protection features include over-voltage protection (OVP), over-current protection (OCP), and thermal shutdown. The MP8869S is available in a QFN-14 (3mmx4mm) package. FEATURES Vout Adjustable up to 5.5V using FB pin Wide 2.85V to 18V Operating Input Range 12A Continuous/15A Peak Output Current 1% Internal Reference Accuracy I2C-Programmable Reference Range from 0.6V to 1.108V in 4mV Steps with Slew Rate Control 5% Accuracy Output Voltage and Output Current Monitoring via I2C Selectable PFM/PWM Mode, Adjustable Frequency and Current Limit through I2C Four Different Selectable I2C Addresses External Soft Start (SS) Open-Drain Power Good (PG) Indication Output Over-Voltage Protection (OVP) Hiccup/Latch-Off Over-Current Protection (OCP) Available in a QFN-14 (3mmx4mm) Package APPLICATIONS Solid-State Drives (SSD) Flat-Panel Televisions 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.
