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.

FEATUREs
Multi-Phase Power Conversion with Automatic Phase Selection
6-bits VRD10.x DAC Output with Active Droop Compensation for Fast Load Transient
Smooth VCORETransition at VID Jump
Power Stage Thermal Balance by DCR Current Sense
Hiccup Mode Over-Current Protection
Programmable Switching Frequency (50kHz to 400kHz per Phase), Under-Voltage Lockout and SoftStart
High Ripple Frequency Times Channel Number
28-TSSOP Package
RoHS Compliant and 100% Lead (Pb)-Free
