Part Number: TPS923655 Hello Lucia,
I started a discussion in TI-Forum regarding LED driver TPS923655 and you asked me to contact you by email, regarding my questions. Unfortunately I did not get eny rersponse on my Email contact. So I try this way…
Part Number: TPS923655 Tool/software: Is there an updated or final version of the Excel-Calculation tool available? I want to use the IC at its limit - this means 48 Input-Voltage, 62V Output-Voltage with 4A. Do you see a problem here?
Part Number: TPS923655 Tool/software: Hi,
Is there a calculation tool for buck-boost version? The one available on forum seems to missed it.
Regards
Michal
Part Number: TPS923655 Tool/software: The following circuit is connected to 18 LEDs and supplied with 24 V. It is supposed to supply ~51,5V at 0,15 A to the LEDs. As soon as I connect the powersupply it burns and a short is created between the SW and…
Part Number: TPS923655 Hi
The high-contrast LED driver has been confirmed to have a 1000:1 power consumption ratio, as the current solution appears to be designed for professional monitors, but it actually needs to be used in notebook computers.
Part Number: TPS923655 Other Parts Discussed in Thread: TPS92692-Q1 Hi,
We are planning to use TPS923655HMDMTR for driving 15 Nos LEDs (with Vf range 2.8V to 3.6V) with 1.5A current and all LEDs in series. Our battery input voltage ranges from 8V -16V…
Part Number: TPS923655 Tool/software: We purchased the eval kit for this part & tested with a signal generator... Everything looked good.
We made a Rev A design with my own layout, 1oz Cu, 4 layers... While it worked, our power supply folded back after…
Part Number: TPS923655 Tool/software: Hello, I try to find some information about the calculation of power dissipation of the IC for different operation conditions. I tried the preliminarry Excel calculation tool and there for my operation conditions…
