Hi Team,
We have planned to use this part LM3410XSD/NOPB for LED driver.
We have to control single IR LED. Maximum current of LED is 50mA. So we adjusting the current from 0 mA to 50 mA.
Vin is battery voltage(4.2V) and our required output voltage is 3.3V.
Kindly please find below image for our circuit. As per datasheet the inductor value mentioned 4.7uH. But inductor frequency not mentioned.
could you please suggest what inductor frequency we need to select. DIM pin we are connected to GPIO port of microcontroller(MSP430F5438AIPZ)
We have using the DIM for LED Driver ON/OFF Purpose.
