Hi Henry,
I have another recommendation to you. It is LM3645, RTMed next month. 4-ch flash, 360mA torch per-channel. I think customer could shunt 4 channels together to use.
Thanks！
Best,
John.
Part Number: LM3553 I want to use a LM3553 to drive a string (series) of 2 white LED in a camera flash application. Input voltage is 5V.
I understand that maximum ID1+ID2 = 1.2A which corresponds to Rset = 14kR.
By setting bit ST1=0 and bit ST0=0 the stepping…

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…

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: 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…
