Preliminary RT8801B Multi-Phase PWM Controller for K8 CPU Core Power Supply with Serial Programming Interface General Description The RT8801B is a multi-phase synchronous buck controller which is implemented with full control functions for AMD K8 compliant CPU. The RT8801B could be operated with 2, 3 or 4 buck switching stages operating in interleaved phase set automatically. The multiphase architecture www.DataSheet4U.com provides high output current while maintaining low power dissipation on power devices and low stress on input and output capacitors. RT8801B is one of RichTek CPU core power solutions which integrates a specific series programming interface for the controller peration configuration.
