DC2164A-B，演示電路 2164A-B 采用 PolyPhase 設計，采用三個 LTM4630EY-1 高效率、高密度、雙路 18A、開關模式降壓
電源模塊穩壓器。輸入電壓為4.5V至15V。輸出電壓可通過跳線選擇，可設置為 0.9V、1.0V、1.2V、1.5V 或 1.8V。 DC2164A-B 可提供標稱 105A 輸出
電流。如數據表中所述，對于某些 VIN、VOUT 和熱條件，輸出電流降額是必要的。 DC2164A-B 上的 LTM4630-1A 始終以連續導通模式運行。開關頻率可以通過
電阻器進行編程，也可以與外部
時鐘信號同步。該板允許用戶對其輸出電壓如何通過 TRACK 引腳升高和降低進行編程

DC2164A-B, Demonstration Circuit 2164A-B features a PolyPhase design using three LTM4630EY-1 high efficiency, high density, dual 18A, switch mode step-down power module regulator. The input voltage is from 4.5V to 15V. The output voltage is jumper selectable and can be set to 0.9V, 1.0V, 1.2V, 1.5V or 1.8V. The DC2164A-B can deliver nominal 105A output current. As explained in the data sheet, output current derating is necessary for certain VIN, VOUT and thermal conditions. The LTM4630-1A on DC2164A-B always operate in continuous conduction mode. The switching frequency can be programmed through a resistor or can be synchronized to an external clock signal. The board allows the user to program how its output voltage ramps up and down through the TRACK pin
