General Description

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 “standby 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

Key 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 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 c.
