具有集成鐵氧體磁珠濾波補(bǔ)償?shù)?17V 輸入電壓、3A 低噪聲、低紋波降壓模塊

TPSM8291x 器件是一系列高效、低噪聲和低紋波電流模式同步降壓電源模塊。這些器件非常適合通常使用 LDO 實(shí)現(xiàn)后置穩(wěn)壓的噪聲敏感型應(yīng)用，例如高速 ADC、時(shí)鐘和抖動清除器、串行器、解串器和雷達(dá)應(yīng)用。\n\n這些器件在 2.2MHz 或 1MHz 的固定開關(guān)頻率下工作，并可與外部時(shí)鐘同步。\n\n為了進(jìn)一步減小輸出電壓紋波，器件集成了環(huán)路補(bǔ)償，可與可選的第二級鐵氧體磁珠 L-C 濾波器一起工作。該功能可將輸出電壓紋波降至 10μVRMS 以下。\n\n通過使用 NR/SS 引腳上的集成電容器對內(nèi)部電壓基準(zhǔn)進(jìn)行濾波來實(shí)現(xiàn)類似于低噪聲 LDO 的低頻噪聲水平。可以在模塊中添加一個(gè)外部電容器以進(jìn) ? 低輸出 1/f 噪聲 RMS （100Hz 至 100kHz）\n? 大于 65dB 的高 PSRR（高達(dá) 100kHz）\n? 可與外部時(shí)鐘同步（可選）\n? 展頻調(diào)制（可選）\n? 0.8V 至 5.5V 輸出電壓范圍\n? 輸出電壓精度為 ±1%\n? 用戶定義的欠壓鎖定\n? 可調(diào)節(jié)軟啟動\n? 輸出放電（可選）\n? -ET 版本為 –55°C 至 125°C\n? 使用 TPSM8291x 并借助 WEBENCH Power Designer 創(chuàng)建定制設(shè)計(jì);
