Other Parts Discussed in Thread: LM3492HC-Q1 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…
Other Parts Discussed in Thread: LM3492HC-Q1 , LM3492-Q1 I wolud like to confirm the thermal resistance of LM3492HC-Q1.
The customer wants to know it.

Other Parts Discussed in Thread: LM3492HC-Q1 I would like to confirm the solution of the Audible noise for LM3492HC-Q1.
In the datasheet page1, there is the comment of the audible noise "The application circuit is stable with ceramic capacitor - produces…
I would like to confirm EN pin voltage.
I can not find the specification of EN pin volltage maximum rating.
How much is it?
There is the possibility of the supply voltage 5.2V.
Best regards,
Atsushi Yamauchi
There is the variation with Tj of quiescent current for shutdown mode in the datasheet page 6. The customer wants to know the data around VIN 10 to 20V, but we can not check the value with temperature variation.
Can you provide the data scale-up VIN…
Part Number: LM3492HC Hello Team,
Could you help me check if below calculation to check if LM3492HC-Q1 contrast ratio and input clamping current meet the system specs?

Via the calculation, the LED driver…
Other Parts Discussed in Thread: LM3492HC , LM3492 It is not clear what happens if resistor Rfb1 is too high or even is an open circuit.
Q1 : What then becomes the value of Vout and can this (possibly too high) value damage the LM3492HC ?
Q2 : Is…
