  Exposed Pad LQFP The LTCВ®3676 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, and system
  on-chip (SoC) rails and three 300mA LDO regulators for
  low noise analog supplies. The LTC3676-1 has a В±1.5A
  buck regulator configured to support DDR termination ...
