Pin No Pin Name Pin Function 14, 15, 19, 20, 21 NC No internal connection. 16, 17 PWM[1:2]_MAIN PWM outputs for main rail VR of Channel 1 and 2. 18 DRVEN_SET Set DRVEN output function at PS4. Set to 5V DRVEN is floating, and set to GND DRVEN is low at PS4. 22 PWM_AUXI PWM outputs for auxiliary rail VR. 23 TSEN_AUXI Thermal sense input for AUXI rail VR. 24 FB_AUXI Negative input of the error amplifier. This pin is for auxiliary rail VR output voltage feedback to controller. 25 RGND_AUXI Return ground for auxiliary rail VR. This pin is the negative node of the differential remote voltage sensing. 26 COMP_AUXI Auxiliary rail VR compensation. This pin is error amplifier output pin. 27 VSEN_AUXI Auxiliary VR voltage sense input. This pin is connected to the terminal of Main VR output voltage. 28 ISENN_AUXI Negative current sense input of single-phase auxiliary Rail. 29 ISENP_AUXI Positive current sense input of single-phase auxiliary Rail. 30 IMON_AUXI Auxiliary rail VR current monitor output. This pin outputs a voltage proportional to the output current. 31 VR_HOT Thermal monitor output, this pin is active low. 32 VDIO VR and CPU data transmission interface. 33 ALERT SVID alert. (Active low) 34 VCLK Synchronous clock from the CPU. 35 DRVEN External driver enable control. Connecting to driver enable pin. 36 PWM_SA PWM outputs for VCCSA VR. 37 EN VR enable control input. 38 VR_READY VR ready indicator. 39 IMON_SA VCCSA rail VR current monitor output. This pin outputs a voltage proportional to the output current. 40 ISENP_SA Positive current sense input of single-phase VCCSA rail VR. 41 ISENN_SA Negative current sense input of single-phase VCCSA rail VR. 42 VREF06/PSET Fixed 0.6V output reference voltage. This voltage is used to offset the output voltage of IMON pin. Between this pin and GND must be placed a exact 0.47 F decoupling capacitor and 3.9 resistor. 43 COMP_SA VCCSA rail VR compensation. This pin is error amplifier output pin. 44 RGND_SA Return ground for VCCSA rail VR. This pin is the negative node of the differential remote voltage sensing. 45 FB_SA Negative input of the error amplifier. This pin is for VCCSA rail VR output voltage feedback to controller. |
