Need BAcklight LED Driver

Hi Rajesh,

Please check LT3519-2.

Hi Rajesh,

Please check LT3519-2.

Thanks Fil.

LT3519-2 is a boost LED driver, we can't use this in our application.

I require a low side programmable current sink device for backlight LED application.

LED operating voltage range is 26V - 29V and typical current is 50mA, max can go upto 100mA. Voltages to the backlight LEDs are available on-board.

I am looking for a suitable one channel current sink device which can have option for analog / pwm dimming. 

Please suggest few economical options which can meet operating temp range of -40 to +70degC.

Thanks & Regards,

Rajesh Kumar

Hi Rajesh,

Please connect to a local ADI FAE who may be able to help you better.

Hi Fil,

Sure, I will try to contact a local ADI FAE.

Meanwhile request you to review the circuit implementation using ADP8140. Shall I post my circuit here?

Regards,

Rajesh

For ADP8140, you may post in the other thread where you had ADP8140 in the title. Or if not, you may send me friend request so you can send to my email address.

Yes, I have sent you a friend request through ADP8140 thread, please accept it.

Rajesh
