Functional Pin Description Pin No Pin Name Pin Function 1 IMON_MAIN Main rail VR current monitor output. This pin outputs a voltage proportional to the output current. 2 SET1 Platform setting. Platform can use this pin to set switching frequency, ki gain, QRTH, QR width and anti-overshoot for Auxiliary VR. Connect the SET1 pin to 5V and turn-on the EN pin, if the soldering is good, VSEN_MAIN = VSEN_AUXI = 1.1V and VSEN_SA = 1.05V. 3 FB_MAIN Negative input of the error amplifier. This pin is for main rail VR output voltage feedback to controller. 4 COMP_MAIN Main rail VR compensation. This pin is error amplifier output pin. 5 SET2 Platform setting. Platform can use this pin to set switching frequency, ki gain, QRTH, QR width and anti-overshoot for MAIN VR. 6 SET3 Platform Setting. Platform can use this pin to set switching frequency, ki gain zero load-line, QRTH and QR width for VCCSA rail. And it can be set DVID_TH and force-non-zero VBOOT function for Main and AUXI rail. 7, 8 ISEN[1:2]N_MAIN Negative current sense inputs of multi-phase main rail VR Channel 1 and 2. 10, 9 ISEN[1:2]P_MAIN Positive current sense inputs of multi-phase main rail VR Channel 1 and 2. 11 TSEN_MAIN Thermal sense input for main rail VR. 12 VIN VIN input pin. Connect a low pass filter to this pin to set on-time. 13 VCC Controller power supply. Connect this pin to 5V and place a decoupling capacitor 2.2 F at least. The decoupling capacitor is as close PWM controller as possible. Ordering Information Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes.
