LT3509，12V 汽车电池电压为 3.3V 和 1.8V，带有保持电容器和 FAULT 指示器

JFET 发布

电路展示了 LT3509、12V 汽车电池至 3.3V 和 1.8V，具有保持电容器和故障指示器。 LT3509 双通道降压稳压器可在 3.6V 至 36V 以上的宽广电源范围内工作，但其真正的显着特点是能够轻松保护自身和下游组件免受高达 60V 瞬态输入电压的影响

说明

  • Circuit shows LT3509, 12V auto battery to 3.3V and 1.8V with hold-up capacitors and FAULT indicator. The LT3509 dual channel step-down regulator operates over AN impressively vast supply range of 3.6V to more than 36V, but its real distinguishing feature is its ability to handily protect both itself and down-stream components from transient input voltages up to 60V
