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 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 co...
