The LTC®3676 is a complete power management solution for i.MX6, ARM Cortex processor systems. The LTC3676 features eight independent resistor-programmable voltage rails, with dynamic control and sequencing, in compact QFN and LQFP packages. These rails supply power to the processor core, SDRAM, system memory, PC cards, always on real-time clock (RTC), and a variety of other functions.
