General Description
RT9245C is a multi-phase buck DC/DC controller integrated with all control functions for AMD K8 CPU or Intel® GHz CPU which is VRD10.x-compliant. The RT9245C could be operated with 2, 3 or 4 buck switching stages operating in interleaved phase set automatically. The multiphase architecture provides high output current while maintaining low power dissipation on power devices and low stress on input and output capacitors. The high equivalent operating frequency also reduces the component dimension and the output voltage ripple in load transient.

FEATUREs
