DC2378A-B 演示
電路采用 LTM4650-1 高效率、高密度、雙路 25A、單路 50A、開關模式降壓
電源模塊穩壓器。輸入電壓為4.5V至15V。輸出電壓可編程范圍為 0.6V 至 1.8V。 DC2378A 可以從每個通道提供 25A 的最大
電流。該板在重負載條件下以連續導通模式運行。為了在低
負載電流下實現高效率，MODE 跳線 (JP1) 為噪聲敏感型應用選擇脈沖跳躍模式，或為噪聲不太敏感的應用選擇突發模式操作。兩個輸出可通過可選的跨接電阻并聯，形成單個 50A 輸出解決方案

DC2378A-B, Demonstration Circuit features the LTM4650-1 high efficiency, high density, dual 25A, single 50A, switch mode step-down power module regulator. The input voltage is from 4.5V to 15V. The output voltage is programmable from 0.6V to 1.8V. DC2378A can deliver 25A maximum current from each channel. The board operates in continuous conduction mode in heavy load conditions. for high efficiency at low load currents, the MODE jumper (JP1) selects pulse-skipping mode for noise sensitive applications or Burst Mode operation in less noise sensitive applications. Two outputs can be connected in parallel for a single 50A output solution with optional jumper resistors
