Part Number: LM3405A 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 than the ~80% efficiency indicated by the data sheet…
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, but…
Part Number: LM3405A Dear Sir,
We are looking for the development of a 1A Constant Current LED driver using similar IC's like LM3405A
Green LED Forward Voltage: 3.0v - 3.6v Typical Voltage: 3.1v Typical Forward Current: 700mA Qty:2 No's
Red LED Forward…
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…
Part Number: LM3405A Other Parts Discussed in Thread: LM3405 , LM3406 , TPS92515 , TPS92511 I am working on an LED retrofit to be used with an AC-dimming Halogen lamp supply. (10,000 units in the field!)
This will be running a single white LED at about 1…
Part Number: LM3405A Other Parts Discussed in Thread: LM3405 , , TPS92515 , TPS92518 , LM3409 Hello,
we use in our application 2 LM3405 devices.
Each of the LM3405A drives a Group of 4 LED´s in series.
Both of the LM3405A get the same PWM-Signal at the…
