MP8847 6A, 2.7V-6V, High-Efficiency, Synchronous, 2 Step-Down Switcher with I C Interface In 2x3mm QFN The Future of Analog IC Technology DESCRIPTION FEATURES 2 The MP8847 is a highly integrated, high- I C-Programmable Output Range from 0.6V frequency, synchronous, step-down switcher to 1.235V in 5mV Steps 2 with an I C control interface. The MP8847 can 2.7V to 6V Input Voltage Range support up to 6A of load current over an input Up to 6A Load Current supply range from 2.7V to 6V with excellent Internal 35m High-Side and 15m Low- load and line regulation. Side Power MOSFETs 2 I C-Compatible Interface up to 3.4Mbps Constant-frequency hysteretic mode provides Factory Adjustable Switching Frequency an extremely fast transient response without from 0.85MHz to 2.2MHz loop compensation to achieve high efficiency 2 Power-Saving Mode Selectable via I C easily under light-load condition. Internal 1ms Soft Start The output voltage level can be controlled on- Power Good Indicator 2 the-fly through a 3.4Mbps I C serial interface. Current Overload and Thermal Shutdown The voltage range can be adjusted from 0.6V to Protection 1.235V in 5mV steps. The voltage slew rate, Available in 2mmx3mm QFN-14 Package switching frequency, and power-saving mode 2 are also selectable through the I C interface. APPLICATIONS Full protection features include internal soft Processor Core Supplies start, over-current protection (OCP), and over- Micro Converters temperature protection (OTP). All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under The MP8847 requires a minimal number of Quality Assurance.
