We are using LM3404 in one of the designs.
The Vin =12V, Vf =2.1V, No of led -2 If =1A.
I have a clarification regarding the Switching Frequency & Ron value. As per the datasheet page 9 figure 14 .
For a Vf of around 4V the Switching Frequency should be 1000KHz. In such a condition my Ron value is around 32.8K. ton is 360ns
However in Page 6 Switching characteristic is mentioned that that Ton should be within 2.1uS to 3.4uS.
Kindly clarify.
