Part Number: LM3405A Tool/software: Hi team,
Request you to share the SPICE model of the IC LM3405A. And also please let me know if I can share my current sense circuit which is currently in use and you can simulate and see whether we can use the…
Part Number: LM3405A Hi Teams,
When using LM3405A, my input voltage is "3.8V - 4.2V", and the If and Vf of the loaded LEDs are: 100mA 1.61V, 200mA 1.88V, 300mA 2.14V, 400mA 2.40V. I want to parallel two LEDs, and R1 uses 0.2 ohm to make the output current…
Part Number: LM3405A Other Parts Discussed in Thread: TPS60230 Tool/software: Hello, I have a 3.5" LED backlight with the following electrical specifications (10 LEDs connected in parallel, K1 to K10 tied together):
The client device uses a single…
Part Number: LM3405A Other Parts Discussed in Thread: TPS923655 Hello:
We have an IC that was previously selected as LM3405axmk, with a maximum current of 1a and an input of 5V-22V, with a linear step-down.
We used to input 5V with one 3V LED, but…
Part Number: LM3405A Other Parts Discussed in Thread: TPS92200 Tool/software: Hi,
The worst-case maximum duty cycle specified in the datasheet is 85%. This I assume is the specification across the full operating temperature range and accounting for…
Part Number: LM3405 Other Parts Discussed in Thread: TPS92200 , , TPS92201 Tool/software: Also LM3405A. The graphs in the datasheet show an output current range of 200-1000mA. Are there any problems going lower than 200mA? We need 100mA. I tried 20mA…
Part Number: LM3405A Other Parts Discussed in Thread: TPS922052 , TPS92200 Tool/software: It is being developed by applying LM3405A LED Driver IC. Currently, high-frequency noise has occurred during the testing and has been improved in various ways, but…
Part Number: LM3405A
Hi, TI expert
There is a request for a schematic review using the LM3405A from a customer.
The circuit diagram is attached as below.
Customer wanted to use 4 LED VF 1.5V in series, but because the BOOST PIN is 5.5V the…
