I would like to confirm the switching frequency of LM3492HC-Q1.
In the datasheet 10 page, there is the figure RRT vs switching frequency.
What is the condition for the figure? Does the frequency change with the load current?
And the customer sets 680kohm for the frequency about 200kHz, but the frequency is 180kHz (with Vin=12V, Iload=250mA).
Is this correct?
Best regards,
