Part Number: TPS922055 Other Parts Discussed in Thread: TPS922052 , TPS922054 , TPS922053 Hi,
One of my customer is working on TPS922055 based LED drvier & facing strange issue. Driver is working ok in normal use casebut when driver is in off state at that…
Hi Florian,
You are welcome.
There are lots of factors that determine the maximum number of LEDs TPS92205x can drive under a specific input voltage, for example -
Thermal consideration - Driving larger number of LEDs means higher switching duty cycle…
Part Number: TPS922055DMTREVM Other Parts Discussed in Thread: TPS922055 Tool/software: Hi, I am working on a LED driver design using TPS922055 as driver for 2 Cree XFL05K-00-0000-0B0H0A0E3 LEDs (Vfv 6v), connected in parallel. Power supply will be 2 LiIon…
Hi Alex,
You are welcome.
Please follow the E2E FAQ at this time ( [FAQ] How to design the CSP and CSN pin components for TPS922055 / TPS922054 / TPS922053 / TPS922052? - Power management forum - Power management - TI E2E support forums ). Current datasheet…
Part Number: TPS922055DRRREVM Other Parts Discussed in Thread: TPS922055 , Tool/software: Hello,
we want to use the TPS922055 for the illumination of a camera. Currently we have a testsetup with the eval kit TPS922055DRRREVM. For this case we need a high…
Hi Jiang,
Steven Li said: It is hard for 1 pcs TPS923654 HM DMTR to work in application conditions of Vin = 15V, Vout = 33V, I_out = 2.38A in Boost topology due to thermal concern. You may need to parallel 2 pcs TPS923654DMTR / TPS923654DRRR to achieve this…
The modulation is caused by the spread spectrum feature of the TPS922055 device. I have searched the datasheet before for 2 kHz, but it is written as 2-kHz, hence did not deliver any matches. I will order the TPS922 052 device, and all should be good. …
Hi Joel,
Based on my knowledge, some 24V LED strip in the market need a constant-voltage source to drive and there are current-limiting resistors on the strip. TPS922053 / TPS923653 is not a good candidate to drive such LED strips.
If you remove the current…
Part Number: TPS922052 Other Parts Discussed in Thread: TPS922055 , TPS922053 , TPS922053DYYREVM Tool/software: LED team,
We have a customer wanting to evaluate the TPS922052, so they will test with TPS922053DYYEVM. The LEDs used by the customer are rated…
Hi Jonathon,
For "Dimming Mode Start", please refer to this E2E FAQ ( [FAQ] How will TPS922055 / TPS922054 / TPS922053 / TPS922052 transform from shutdown into hybrid dimming mode? - Power management forum - Power management - TI E2E support…
