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 the…
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 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 now…
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? (specification…
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: 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 purposes…
hi kim
Glad to hear that. Would you mind my asking the application here for LM3405 and why this is chosen? Does the reason is that this can support Vin down to 3V?
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 maximum…
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…
