com RT9241A/B Two-Phase DC/DC Controller for CPU Core Power Supply General Description The RT9241A/B is a two-phase buck DC/DC controller integrated with all control functions for high performance processor VRM.
The RT9241A/B drives 2 buck switching stages operating in 180 degree phase shift.
The two-phase 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.
RT9241A/B regulates both easily set voltage and current loops.
Precise current sharing for power stage is achieved by differential input current sense and processing circuit.
The settings of current sense, droop tuning and over current protection are independent to compensation circuit of voltage loop.
The feature greatly facilitates the flexibility of CPU power supply design and tuning.
