Hi Lorenzo,
Since LM3553 is an older device, the designers can't find the database of this device. Therefore, they are not sure what's causing the noise.
Hope you can run your tests well, we will continue to try our best to solve problems for…
Part Number: LM3553 Other Parts Discussed in Thread: LM3644 Hi
I would like to ask you to recommend an IC with or without the same function
A. It needs to be a flash (I want to drive two leds, one needs 1A)
B. Also test Torch (the same two, but I think…
Part Number: LM3553 Hi support :
LM3553 driving Vf 3.3V Red LED is ok.
But I change Vf 3.3V Red LED to a new OSRAM GR PSLR31.13 LED.
The Vf of GR PSLR31.13 is about 6.6V.
When turn on the LED.
There is a high frequency noise.
Maybe the noise come from…
Part Number: LM3553 Other Parts Discussed in Thread: LM36010 , LM3560 , , TPS92200 I'm looking to drive two LEDs for a project. Flip Chip 10 by Lumiled LED Vf=2.77V at 350mA
Due to the low Vf, ICs like the LM3560/LM36010 that I've used in previous projects…
Part Number: LM3553 Other Parts Discussed in Thread: LM36010 Hi, Team
My customer is working with LM3553 in a application of drive 1* LED. Power supply is 5V only.
LED: VF ID
Max: 3.5V 350mA
Min: 2.9V 100mA
They are using the single LED schematic…

But I could not find GUI.
Where can i download the GUI in TI site?
Part Number: LM3553 Other Parts Discussed in Thread: LM3643 , LM3644 Hi team,
Customer inquired PWM brightness control possibility by adding PWM signal to the FEN pin.
I is thought that the flash operation is repeated synchronizing to the high transition…
Part Number: LM3553SDEV Other Parts Discussed in Thread: USB2ANY , LM3553 Hello, I received the LM3553SDEV kit today with no software. Can you please share a link to download the software. Best Regards.
Part Number: LM3553 Hi team,
Customer want to use LM3553 with the following specification.
VIN = 3.3V
LED : Vf=1.5V – 2.1V, If = about 400mA, 2-parallel×5-sleaze
ON time = 0.5ms, period = 5.56ms, synchronizing 2-parallel,
Is this possible…
