Data Sheets:
The MIC7401 is a powerful, highly integrated, configurable, power-management IC (PMIC) featuring five synchronous buck regulators, one boost regulator, and a high-speed I2C interface with an internal EEPROM.The device offers two distinct modes of operation 'stand-by mode' and 'normal mode' intended to provide an energy-optimized solution suitable for portable handheld, and infotainment applications.In normal mode, the programmable switching converters can be configured to support a variety of features, including start-up sequencing, timing, soft-start ramp, output voltage levels, current-limit levels, and output discharge for each channel. In stand-by mode the PMIC can be configured in a low power state by either disabling an output or by changing the output voltage to a lower level. Independent exit from stand-by mode can be achieved either by I2C communication or by the external STBY pin.
The device has five synchronous buck regulators with high-speed adaptive on-time control that supports even the most challenging ultra-fast transient requirement for core supplies. One boost regulator provides a flash-memory programming supply that delivers up to 200mA of output current. The boost is equipped with an output disconnect switch that opens if a short-to-ground fault is detected.An internal EEPROM enables a single-chip solution across many platforms by allowing the designer to customize the PMIC for their design. Modifications can be made without the need to re-approve a new PMIC, saving valuable design resources and time. All switchers provide light-load efficiency with HyperLight Load® mode for buck and PFM mode for boost. An additional benefit of this proprietary architecture is very-low output ripple voltage throughout the entire load range with the use of small output capacitors. The MIC7401 is designed for use with a small inductors (down to 0.47µH for buck, 1.5µH for boost), and an output capacitor as small as 10µF for buck, enabling a total solution size of 12mm x 8.5mm and less than 1mm height on the top layer.
