Device Overview

Summary

The MIC7400 is a powerful, highly-integrated, configurable, power-management IC (PMIC) featuring five synchronous buck regulators, one boost regulator, and 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 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 the external STBY pin.

The device has five synchronous buck regulators with high-speed adaptive on-time control, supporting even the 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 MIC7400 supplies are designed for use with a small inductor (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 15mm × 15mm and less than 1mm height.
