Product Overview

The LTC3589EUJ-2#PBF is a 8-output Regulator with sequencing and I2C and a complete power management solution for ARM and ARM-based processors and advanced portable microprocessor systems. The device contains three step-down DC/DC converters for core, memory and SoC rails, a buck-boost regulator for I/O at 1.8 to 5V and three 250mA LDO regulators for low noise analog supplies. An I2C serial port is used to control enables, output voltage levels, dynamic voltage scaling, operating modes and status reporting. Regulator start-up is sequenced by connecting outputs to enable pins in the desired order or programmed via the I2C port. System power-on, power-off and reset functions are controlled by pushbutton interface, pin inputs or I2C interface. The LTC3589 supports i.MX53/51, PXA and OMAP processors with eight independent rails at appropriate power levels.
