42 V、15 A同步降壓型超低噪聲開關穩(wěn)壓器2

LT8642S同步降壓型穩(wěn)壓器采用第二代Silent Switcher架構，盡可能地降低了EMI發(fā)射，同時在高開關頻率下實現(xiàn)了高效率。其中包含集成旁路電容以優(yōu)化內(nèi)部所有快速電流環(huán)，并通過消除布局敏感性輕松實現(xiàn)宣傳的EMI性能。\n\n 快速、干凈、低過沖開關邊沿即使在高開關頻率下也可以實現(xiàn)高效率工作，從而提供小型整體解決方案。具有20ns最短接通時間的峰值電流模式控制，即使在高開關頻率下也能實現(xiàn)高降壓比。通過VC引腳進行外部補償，可在高開關頻率下實現(xiàn)快速瞬態(tài)響應。CLKOUT引腳使其他穩(wěn)壓器可同步到LT8642S。\n\n 突發(fā)工作模式可實現(xiàn)低待機功耗，強制連續(xù)模式可以控制 ?
