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 …
