uP9521R Dual Output 4+3-Phase PWM Controller with SMBus Digital Interface Control for IMVP8 General Description The uP9521R is an IMVP8 compliant desktop CPU voltage regulator controller that integrates a 4-phase PWM controller for Vcore and a 3-phase PWM controller for VccGT. The Vcore controller can be configured as 4/3/2/1phase and the VccGT controller can be configured as 3/2/ 1-phase for platform power design flexibility. This part outputs PWM signal to external MOSFET driver to drive the buck power stage. The integrated SMBus interface programmability makes this part with high performance and easy design. Designer can define different power scenario for different current states to optimize the performance and efficiency.
