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