DC721A-B - LTC3738CUHF Demo Board | 3-Phase, 8V ≤ VIN ≤ 14V, Vout = VRM9.X / 10.X @ 65A
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 DC721A-B is a single LTC3738 3-phase 65A output supply. The input voltage range for both demo boards is from 8V to 14V, and the output voltage is controlled by the VID setting.
