4.5V 至 18V 輸入電壓完整 DDR4 存儲器電源解決方案

TPS65295 器件能夠以最低的總成本和最小的空間為 DDR4 存儲器系統(tǒng)提供完整的電源解決方案。它符合 JEDEC 標準中的 DDR4 加電和斷電順序要求。TPS65295 將兩個同步降壓轉(zhuǎn)換器（VPP 和 VDDQ）與 1A 灌電流和拉電流跟蹤 LDO (VTT) 以及緩沖低噪聲基準 (VTTREF) 集成在一起。TPS65295 采用耦合了 600kHz 開關(guān)頻率的 D-CAP3?模式，此模式可在無需外部補償電路的情況下實現(xiàn)易于使用的快速瞬變并支持陶瓷輸出電容器。\n\nVTTREF 跟蹤 ? VDDQ 的精度優(yōu)于 0.8%。VTT 可同時提供 1A 持續(xù)灌電流和拉電流功能，而 ? 同步降壓轉(zhuǎn)換器 (VDDQ) \n? 輸入電壓范圍：4.5V 至 18V \n? 輸出電壓固定為 1.2V \n?
