The VDD controller can be configured as 4/3/2/1-phase, and the VDDA controller can be configured as 2/1/0-phase (0 denotes VDDA controller is disabled) for platform power design flexibility. This part integrates 2 bootstrap diode embedded 12V MOSFET drivers. For the typical 4+2-phase application, the 4-phase VDD controller has 2 embedded MOSFET driver and 2 PWM outputs. The 2-phase VDDA controller has 2 PWM outputs. The controller provides further flexible operating phase configurations to support 6+0 or 5+1 phase application (0 denotes VDDA controller is disabled). 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. The uP9504 combines true differential output voltage sense, differential inductor DCR current sense, input voltage feed- forward sense and adaptive voltage positioning to provide accurately regulated power for desktop CPU. It adopts uPI proprietary RCOT+TM (Robust Constant On-Time) topology to have fast transient response and smooth mode transition. Similar to digital based PWM controller, the loop gain is also programmable by SMBus interface to achieve design flexibility. The uP9504 has built-in serial interface to communicate with AMD SVI2 compliant CPU. It supports mode transition function with various operating states. This part provides two different VID on-the-fly slew rates, which can be programmed by the SMBus register. The uP9504 provides power good indicator and selectable VR parameters, such as SMBus device address and Vboot voltage. It also provides complete fault protection functions, including over voltage, under voltage, over current, over temperature and under voltage lockout. The uP9504 is available in VQFN7x7-60L package.
