MP8861 2.85V - 18V, 6A, High-Efficiency, Wide-Input, Synchronous, Step-Down Converter with 2 Integrated Telemetry via I C Interface The Future of Analog IC Technology DESCRIPTION FEATURES The MP8861 is a high-frequency, synchronous, Wide 2.85V to 18V Operating Input Range rectified, step-down, switch-mode converter 6A Continuous Output Current 2 with an I C control interface. The MP8861 offers 1% Internal Reference Accuracy 2 a fully integrated solution that achieves 6A of I C Programmable Reference Range from continuous output current with excellent load 0.6V to 1.108V in 4mV Steps with Slew and line regulation over a wide input supply Rate Control range. 5% Accuracy Output Voltage and Output 2 Current Monitoring via I C The output voltage level can be controlled on- 2 Selectable PFM/PWM Mode, Adjustable the-fly through an IC serial interface. The 2 Frequency and Current Limit through I C reference voltage range can be adjusted from 2 Four Different Selectable I C Addresses 0.6V to 1.108V in 4mV steps. The voltage slew rate, frequency, current limit, hiccup/latch-off External Soft Start (SS) protection, enable, and power-save mode (PSM) Open-Drain Power Good (PG) Indication 2 are also selectable through the I C interface. Output Over-Voltage Protection (OVP) Hiccup/Latch-Off Over-Current Protection Constant-on-time (COT) control operation (OCP) provides fast transient response. An open-drain VOUT Adjustable up to 5.5V using FB pin power good (PG) pin indicates that the output Available in a QFN-14 (3mmx4mm) voltage is in the nominal range. Full protection Package features include over-voltage protection (OVP), over-current protection (OCP), and thermal APPLICATIONS shutdown. Solid-State Drives (SSD) The MP8861 is available in a QFN-14 Flat-Panel Televisions and Monitors (3mmx4mm) package.
