RT8801B
Description
The RT8801B is a multi-phase synchronous buck controller which is implemented with full control functions for AMD K8 pliant CPU. The RT8801B 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. RT8801B is one of Rich Tek CPU core power solutions which integrates a specific series programming interface for the controller peration configuration. There are several registers implemented for the specific parameters configuration including VID for core power, and signal for load current indication. User can program the configuration of the parameters easily via the specific programming interface. With the implementation of RT8801B, the part provides more flexibility and feature for customers advanced segment product design. The RT8801B applies the DCR sensing...
