www.DataSheet4U.com RT9245 Multi-Phase PWM Controller for CPU Core Power Supply General Description RT9245 is a multi-phase buck DC/DC controller integrated with all control functions for Intel® GHz CPU which is VRD10.X-compliant. The RT9245 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. The high equivalent operating frequency also reduces the component dimension and the output voltage ripple in load transient. RT9245 implements both voltage and current loops to achieve good regulation, response and power stage thermal balance.
