Product Overview

The LTC3676ILXE#PBF 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, system on-chip (SoC) rails and three 300mA LDO regulators for low noise analog supplies. The LTC3676-1 has a ±1.5A buck regulator configured to support DDR termination plus a VTTR reference output. An I2C serial port is used to control regulator enables, power-down sequencing, 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 via the I2C port. System power-on, power-off and reset functions are controlled by pushbutton interface, pin inputs or I2C. The LTC3676 supports i.MX, PXA and OMAP processors with eight independent rails at appropriate power levels.
