Preliminary RT8801 Multi-Phase PWM Controller for CPU Core Power Supply with Serial Programming Interface General Description The RT8801 is a multi-phase synchronous buck controller which is implemented with full control functions for Intel® VR10.0/10.1-compliant CPU. The RT8801 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 www.DataSheet4U.com low power dissipation on power devices and low stress on input and output capacitors. RT8801 is one of RichTek CPU core power solutions which integrates a specific series programming interface for the controller operation configuration.
