Part Number: TPS92512 Hi Team,
Please help to check the customer schematics!
Customer feedback the TPS92512 cannot work.
Vin=5V and Vout is 3.3V/1.4A for IR LED.
Thanks.
Part Number: TPS92512 Other Parts Discussed in Thread: TINA-TI Hello,
I would like to ask a question because I need to get the spice model of TPS92512.
I have downloaded TINA-TI and simulated this part but now I would like to transfer it into LTSpice…
Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , Hello,
I am confirming about the difference between TPS92512 and TPS92513. There seem to be two differences. The first seems to be the difference in Iout. The difference between 1.5A and 2…
Part Number: TPS92512 Dear
At present, we use tps92512dgqt for LED driving design. The whole system shares about 30 groups of driving chips, each of which drives 16 lamps. When debugging the current output through 6-pin viadj, it is found that the consistency…
Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , Hello,
Are the TPS92513 and TPS92512 dies the same? The only difference between the two is IOUT and Rds(on), but other electrical characteristics are the same. The Rds(on) is different, but…
Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , , TPS61165 As shown in Figure 3 of SLVA419B in the application note I want to change the LED current by supplying a variable Vref via R1. Is it okay to use this method with TPS92513 / TPS92512…
Part Number: TPS92513 Other Parts Discussed in Thread: TPS92512 , I have a question about the output capacitors (Cout) of TPS92513 and TPS92512. In Typical Application and EVB, Cout is placed between the anode and cathode of the LED. When I checked it with…
Hello,
As shown in he figure,this is the schematic diagram of simulated dimming designed by us. On the same PCB board , we used the same six-way LED driver with the same principle . As the phenomenon desribed
before,when Viadj=0,the output current is…
Part Number: TPS92512 Hello:
I would like to consult my tps92512 for LED dimming, input 16.5v, output 14v-15v, output is connected to 5 LED lights, voltage 14v-15v, The voltage of my IADJ pin is 1.7V. I use a fixed frequency of PDIM for switching. When…
Part Number: TPS92512 Hi,
My customer want to use TPS92512 to adjust current by IADJ pin linearly and put PDIM to high with ISENSE res 0.2R. But they find the output current is not 0 (around 4mA). So I want to check whether this is due to our device limitation…
