LM3409-Q1: LM3409-Q1 UVLO欠压启动问题

Part Number: LM3409-Q1
Other Parts Discussed in Thread: LM3409, DLP5530PGUQ1EVM

您好:

如下图1电路,是TI的DLP5530 DMD评估套件DLP5530PGUQ1EVM中DLP029_LED_Driver_SCH_B原理图中LM3409的电路,输入电压 V_PRE_REG_FILT是8V,根据电路中的电阻参数,参考LM3409规格书P19页图2,

我计算出的 Vturn_on=3.66V, Vhys=0.946V;

这里是原理图中标识错了还是我计算的哪里出问题了?
