具有超低噪声的18V/8A降压型Silent Switcher 3

LT8625S同步降压调节器采用第三代Silent Switcher技术，该技术经过独特设计，将超低噪声基准与Silent Switzer架构相结合，以实现高效和卓越的宽带噪声性能。\n\n 创新的超低噪声架构在开关稳压器中提供了卓越的低频（0.1Hz至100kHz）输出噪声性能。输出电压可以用单个电阻器进行编程，在输出范围内提供单电源操作，从而产生与输出电压无关的几乎恒定的输出噪声。\n\n 静音切换器架构最大限度地减少了EMI发射，同时在高开关频率下提供了高效率。\n\n LT8625S是高电流、噪声敏感应用的理想选择，这些应用得益于同步开关调节器的高效率。 • Silent Switcher® 3架构\n• 超低RMS噪声（10Hz至100kHz）：4μVRMS\n\n• 超低散粒噪声：4nV/√Hz（10kHz时）\n\n• 在任何PCB上具有超低EMI辐射\n\n• 内部旁路电容可降低辐射EMI\n\n\n\n\n• 高频下实现高效率\n\n• 具有高增益误差放大器的超快速瞬态响应\n\n• 输入电压范围：2.7V至18V;
