Part Number: LM3405A Other Parts Discussed in Thread: TPS92612 Hello,
I'm looking for an LED driver that can meet the following specifications. I think the LM3405A is the right device, what do you think? Also, are there any other suitable devices? …
Part Number: LM3405A Other Parts Discussed in Thread: TPS92391 Hi,
we need a constant current drive for our LCD project. The backlight spec is IF=200mA, VF=9V--10.2V. LM3405A datasheet says: Drives up to 5 High-Brightness LEDs in Series at 1A. because…
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 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 Other Parts Discussed in Thread: TPS92200 , TPS54200 Hi TI,
I am trying to make a driver for laser diode. The device consists of 4 laser diodes. Two infrared and one red. This is a medical device and is intended for phototherapy…
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…
Part Number: LM3405A Other Parts Discussed in Thread: LM3405 LED PWM control is being carried out using LM3405A. Designed to be the same as the application notes in the datasheet. The diodes are the same, and for C the internal voltage is slightly higher…
Part Number: LM3405A Dear Specialists,
My customer has a question about Recommended Operating Conditions of LM3405A datasheet and LM3405A Demo Board.
I would be grateful if you could advise.

The LED current is described as IF on the data sheet…
Part Number: LM3405A Other Parts Discussed in Thread: TPS92200 , LM3405 I'm using the LM3405A to drive a single color LED (Vf=2.5, 3.1, or 3.3v) at Iout = 0.7 - 1.0A, with Vin=12v. Based on initial testing, I'm only achieving about 70% efficiency rather…
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…
