Overview
RT9237 Multi-Phase DC/DC Controller for CPU Core Power Supply General Description The RT9237 is a multi-phase buck DC/DC controller integrated with all control functions for high performance processor VRM.
The RT9237 drives 2, 3 or 4 buck switching stages operating in interleaved phase set automatically.
The multi-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.
RT9237 regulates both easily set voltage and current loops.
Precise current sharing for power stage is a...
