uP9521Q
uP9521Q is 4/3/2/1+3/2/1-Phase PWM Controller manufactured by uPI Semiconductor.
4/3/2/1+3/2/1-Phase PWM Controller for IMVP8
General Description
The uP9521Q is an IMVP8 pliant 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 uP9521Q bines the true differential output voltage sense, differential inductor DCR current sense, input voltage feedforward sense and adaptive voltage positioning to provide accurately regulated power for...
