Other Parts Discussed in Thread: LM3481
Our customer is considering the following setting to control LM3481-Q1 on/off, but the voltage range of KL30 is 6~18V, higher than the maximum 6V FA pin can accept from the datasheet. So they're considering to connect a 5.1V zener diode to FA pin to clamp the voltage, but they're not sure if the zener diode will affect the setting frequency accuracy/variation. Would you please give some comments on that? Thanks.
