LTCR3589：8-Output Regulator with Sequencing and I2C

The LTCR3589 is a complete power management solution for ARM and ARM-based processors and advanced portable microprocessor systems. The device contains three synchronous step-down DC/DC converters for core, memory and SoC rails, a synchronous buck-boost regulator for I/O at 3.3V to 5V, and three 250mA LDO regulators for low noise analog supplies. An I2C serial port is used to control regulator enables, output voltage levels, dynamic voltage scaling and slew rate, operating modes and status reporting.
