EV8861-L-00A High Efficiency,6A,18V, Synchronous Step-Down Converter with IC Interface DESCRIPTION FEATURES The EV8861-L-00A is used for demonstrating Wide 2.85V-to-18V Operating Input Range the performance of MPSs MP8861. MP8861 is 6A Continuous Output Current a highly integrated and high frequency 2 1% Internal Reference Accuracy synchronous step-down switcher with I C 2 I C Programmable Output Range from 0.6V control interface. It offers a fully integrated to 1.108V in 4mV Steps with Slew Rate solution that achieves 6A of continuous output Control current with excellent load and line regulation 5% Accuracy Output Voltage and Output over a wide input supply range. 2 Current Read Back Via I C COT control operation provides fast transient Selectable PFM/PWM Mode and Adjustable 2 2 response and eases loop stabilization. In I C Frequency & Current Limit Through I C control loop, the output voltage level can be 2 4 Different I C Address Selectable 2 controlled, on-the fly through an I C serial External Soft Start interface. Output voltage range can be adjusted Open Drain Power Good Indication from 0.6V to 1.108V in 4mV steps. Voltage Output Over Voltage Protection scaling slew rate, enable and power saving 2 Hiccup/Latch off OCP Protection mode are also selectable through the I C QFN-14(3mmx4mm) Package interface. Full protection features include over voltage, over-current protection and thermal APPLICATIONS shut down. Solid State Driver (SSD) The MP8861 is available in QFN-14(3mmx4mm) Flat-Panel Television and Monitors package.
