DESCRIPTION
   The LT®3380 is a complete power management solution for advanced portable application processor-based systems. The device contains four synchronous step-down DC/DC converters for core, memory, I/O, and system onchip (SoC) rails and three 300mA LDO regulators for low noise analog supplies. An I2C serial port may be used to control regulator enables, power-down sequencing, output voltage levels, dynamic voltage scaling, operating modes, and status reporting.
