In summary, the LTC3676 and LTC3676-1 features eight channels: four high-current, high-efficiency step-down regulators, and four low-noise LDOs. Other features include quad I²C adjustable high-efficiency step-down DC/DC converters which operate at 2.5A, 2.5A, 1.5A, 1.5A, and configurable power sequencing. Dynamic voltage scaling output voltage control, a pushbutton interface controller, as well as regulator control via an I²C interface with extensive status reporting, and an interrupt output are also included. The LTC3676/-1 is a complete power management solution for embedded and industrial portable system application processors such as i.MX6, PXA, ARM, OMAP™ and other advanced microprocessor systems. The LTC3676-1 version adds a DDR power solution with VTT and VTTR reference.
