Part Number: TPS65142 Tool/software: Hello,
I asked a question about the constant of R6 in the following thread. Following your answer, my customer created a circuit with R6 set to 0Ω. Then, my customer checked the operation using the created board…
Part Number: TPS65142 Tool/software: Hello,
I am an FAE at a distributor that handles TI products. I received the following question from my customer. In Figure 33 on page 22 of the data sheet, the constant for R6 is not listed. The part circled in red…
Part Number: TPS65142 Other Parts Discussed in Thread: TPS65150 In my application, the LED back light we have I don't think can be controlled with the integrated dimmer. It is a single Anode/Cathode for the LED array and has an IF of 180mA nominal.…
Part Number: TPS65142 Hi,
What is TPS65142 dimming resolution? i didn't find resolution in the datasheet, how to calculate it? For example, if the dimming PWM frequency is 200Hz and 25kHz, what is the corresponding dimming resolution?
Thanks.
…
Part Number: TPS65142 Dear,
we saw the TPS65142 datasheet typical application, VFLK PIN and VGHM PIN was floating?
or MCU GPIO control VFLK?
If any suggestion, Please advise me.
Thanks,
Best regards,
Lawrence.
Part Number: TPS65142 Hi,
Can you explain how to calculate the worst case output voltage tolerance over load/line/temp for the VGL rail for the TPS65142? It looks like there are two parameters - 'reference voltage' and 'reference voltage of feedback'…
Part Number: TPS65142
Customer has started looking at TPS65142 for the requirement of: boost Regulator 6-21V input output 9.2V (+/- 100mv) 2W.
Customer Comments:
3.3V is used to derive 9 and 28V power rails. This is 2 stage conversion with poor matching…
Part Number: TPS65142 Other Parts Discussed in Thread: TPS65150 , TPS65154
Hi all Would you mind if we ask TPS65142 and TPS65150? Our customer are looking for Multiple-Output Regulator which meets the following specifications; <TFT - LCD power spec> Vin…
Hello Vishnu,
Please excuse the extremely late response.
1. Depends on the frequency which creates least issues on your specific screen.
2. If your screen is a 100Hz screen, I would recommend to use another frequency for the dimming.
Best regards, …
