I have this Boost LED Driver IC and this IC is new to me. So, I require some help on how to set the current for my LED String of 300mA. 9LEDs with each forward voltage of 3V and forward current of 300mA.
Can someone help me on how the value of RVFB is calculated for a LED Forward current of 300mA? What equation should I use?
And what should I do with the ADIM pin and OVFB pin in this case?
For switching frequency, suppose I have a 51kohm resistor between FSW and ground, my switching frequency is 980kHz? What factors should I consider to select a correct switching frequency?
For the switching frequency calculation, I used the equation 4 on page 16.
Power LED Datasheet . My requirement is to drive 300mA through an LED String of 9 LEDs.
Can someone help me to calculate on what the input current for the LED Driver IC would be, the switching frequency, what to do with the ADIM & OVFB pin and RVFB value calculation?
