Part Number: LM3550 Tool/software: Hello TI team,
I am using LM3530UME-40/NOPB in one of our designs.
I am not using ALS1, ALS2 and INT pins. Can I leave them open or I need to provide PU/PD to them though I am not using?
Do you have any comments…
Part Number: LM3550 I have used the ELDC supercapacitor - KR-5R5H474-R, it does not have balance pin, Is this correct ?
In my board, Vout is 0V, it is not charging the supercapacitor. is there any alternate for this
attached the schematic below.
Part Number: LM3550 Other Parts Discussed in Thread: TPS65563A Tool/software: hi,
would you like kindly help to recommend a solution to support Photoflash charger, just like LT3468?
Part Number: LM3550 We are sampling a signal directly after the LED flash. The charging is introducing noise and voltage drops to the signal. Currently we see no possibility to manually control the charging. The LM3550 always starts charging when the…
Part Number: LM3550 Good afternoon, I have the circuit shown in the picture and I am trying to use it in optimal mode. I operate using an external strobe signal and my settings are as follow: GENERAL PURPOSE REGISTER= 0x22 CURRENT REGISTER= 0xF8 OPTIONS…
Part Number: LM3550 Other Parts Discussed in Thread: CSD17310Q5A I have a circuit board with a LM3550 that has been validated and working good.
Now I have another board that does not work so well but has the same circuit. I wonder if a wrong part has…
Part Number: LM3550 Hi,
Currently I am using LM3550 for my strobe project.
I am using the same schematic as given by TI as reference design. The problem I am facing is when I am placing the LM3500 in charge mode with the indication LED on,
The indication…
Part Number: LM3550 Hi Team,
For our application we will not be using the optimal charge mode- as set by the Capacitor Charge Level (Table 3). Does this mean that we will not need to worry about the overhead charge voltage? It looks like this value…
Part Number: LM3550 Hello,
I am seeing a fairly large time limit tolerance and just checked the datasheet. the only detail I can see is for the switching frequency - approximately -12% / +15%
Is there a defined tolerance on the on time limit clock…
Part Number: LM3550 Hello,
I have tested two of these ICs and so far both have had a feedback voltage of 80mV even though I have not changed the value of register bank A0, I also set this register bank to F8, but this made no difference.
is there…
