产品详情

演示电路 1687B 采用了 LTC3115-1，后者是一款高电压单片同步降压-升压型转换器。

DC1687B 演示板具有两种用户可选的操作模式：突发模式 (Burst Mode^®) 操作和强制连续操作 (固定频率 PWM) (JP1)。还有一个准确的可编程 RUN 引脚，此引脚用于启用转换器 (JP2)。

DC1687B 在 2.7V 至 40V 的输入电压范围内工作。该演示板的设计将输出电压设定为 5V。LTC3115-1 采用专有的低噪声开关算法，可在输入电压高于、低于或等于输出电压的情况下优化效率，并确保在操作模式之间实现无缝转换。

该演示板被设置为在 PWM 模式中以 1MHz 的频率运行，从而优化小尺寸和高效操作。

该演示板还具有反馈 V_CC的任选配置，以提高某些 5V 输出应用的效率。对于 V_OUT 大于 20V 并需要短路保护的应用，还可在 SW2 和 VOUT 之间连接一个可选的肖特基二极管。有关这些选项的更多信息，请参阅数据手册。

LTC3115-1 数据手册提供了有关该器件工作原理、规格和应用的详细信息。应将数据手册与本快速入门指南配合起来阅读。
