The RT8870A integrated circuit functions as a dual-output PWM controller for powering AMD SVI laptop processors. It controls two-phase power for the CPU core (VDD) and single-phase power for the CPU Northbridge (VDDNB).
It includes three built-in MOSFET drivers and is compatible with AMD’s voltage regulator specification for mobile processors. It uses Richtek’s CCRCOT and G-NAVP control technologies.
