      dc721a-a DC721A-A LTC3738CUHF/LTC3731CUH Demo Board | 6-Phase, 8V ≤ VIN ≤ 14V, VOUT = VRM9.X / 10.X @ 120A Demonstration circuits 721A-A and 721A-B are high current step-down converters for Intel VRM/VRD10 and VRM9 processor power applications. The 6-phase DC721A-A features two current-mode PolyPhaseTM controllers, the LTC3738CUHF (3-Phase Buck Controller for Intel VRM9/VRM10 with Active Voltage Positioning and the the LTC3731CUH (3-Phase, 600kHz, Synchronous Buck Switching Regulator Controller) and provides up to 120A output current. The input voltage is from 8V to 14V and the output voltage is controlled by the VID setting. DC721A-A
