DC1937B，用于 LTC3350EUHF 高电流
超级电容器备用
控制器和系统监视器的演示板，电压高达 20Vin。演示电路 1937B 是一款超级电容器充电器和备用控制器，具有超级电容器运行状况和系统监控功能，采用 LTC3350。 LTC3350 具有一个 10.8V 至 20VIN、5.3A 降压超级电容器充电器、一个 25W 输出备用升压控制器以及一个用于在备用模式下断开输入电源的输入理想二极管。当 VCAP 高于设定的备用电压时，输出理想二极管允许超级电容器提供输出。当电容器组
电压降至设定输出电压时，LTC3350 将作为升压稳压器工作以提供输出，直到超级电容器中的能量耗尽

DC1937B, Demo Board Using for LTC3350EUHF High Current Supercapacitor Backup Controller and System Monitor, up to 20Vin. The Demonstration circuit 1937B is a supercapacitor charger and backup controller with supercapacitor health and system monitoring, featuring the LTC3350. The LTC3350 has a 10.8V to 20VIN, 5.3A buck supercapacitor charger, a 25W output backup boost controller and an input ideal diode to disconnect the input supply in backup mode. An output ideal diode allows the supercapacitors to supply the output when VCAP is above the set backup voltage. As the capacitor stack voltage drops down to the set output voltage, the LTC3350 will operate as a boost regulator to supply the output until the energy in the supercapacitors are depleted
