Part Number: LM3405A I have design LED Driver using above said IC, it is powering up but i cant set current up to 0.75mA @ 12.8V input i have connected 3 white LED in series & 6 in parallel, i required 9 Watt output from driver. As per design reference…
Part Number: LM3405A Hi team,
Could you teach maximum duty cycle over all temperature and input voltage?
I think that the condition of 85% spec. at data sheet is all temperature range, but Vin = 12V.
I checked how LM3405A work when FB=0V at room temp…
Part Number: LM3405A Dear Sir,

The LED current is described as IF on the data sheet, but…
Part Number: LM3405A Other Parts Discussed in Thread: LM3407 , LM3409 Hi,
I see in the LM3405A datasheet, need D2 and boost capacitor to generate boost voltage? why LM3405A need D2 and boost capacitor? in other buck LED driver, only need boost capacitor…
Part Number: LM3405A In one of my application I am using the LM3405A current regulator.
I need to operate the device at current of 80mA which is lower that the recommended current (200mA). However I operate the deice for short pulse of ~0.5mS (so using…
Part Number: LM3405A Other Parts Discussed in Thread: TINA-TI , LM3405 , LM3406 Tool/software: TINA-TI or Spice Models Hi,
How is it possible to do a simulation running the LM3405 when there is no model for it?
Part Number: LM3405A
Hello everyone,
I am looking to drive a display back light. According to the vendor of the display,it is constant current driven. The voltage is typical 9.9V. The typical current is 200mA. Input Voltage is 12V. I wanted to know if…
Part Number: LM3405A Other Parts Discussed in Thread: BQ2002E , Hello,
I want to use the LM3405A as a constant current driver for NiMH cells. In my configuration, I have 2 NiMH cells, and a BQ2002E that regulates the battery charge profile. I want to charge…
