The RT9245A integrated circuit functions as a multiphase PWM controller for powering the cores of AMD K8 processors or Intel processors compliant with VRD10.x. It can operate with 2, 3, or 4 buck converter stages, which automatically synchronize in alternating phases. The multiphase architecture supports high output current while limiting power loss in the power components and reducing stress on the input and output capacitors.
The high effective operating frequency helps reduce component size and output voltage ripple during load transients. The RT9245A uses voltage and current control loops, as well as output inductor DCR sensing technology, for accurate voltage regulation under load.
