Part Number: TPS92520-Q1 Hello, we encountered some problems when using tps92520.
We detected the LED open circuit according to the 3 conditions mentioned in the manual. During the actual test, it is found that the values of each STATUS1 and STATUS2…
Part Number: TPS92520-Q1 hello, i have one question about the TPS92520
the follow is the design data:
input voltage is 50V, the outout voltage is 12v, and the current is 1.3A, when i apply the TPS92520,
as far as i know, the 1.3A is heavy, I think under…
Part Number: TPS92520-Q1 Hi Francis,
I see in datasheet "The internal offset of the device can be measured and compensated using the lower LSBs of the 10-bit CHxIADJDAC." I'd like to know how to measure the offset of one device and how to calculate the…
Part Number: TPS92520-Q1 Other Parts Discussed in Thread: TPS92692 hello
i have one question about the TPS92520 IC,about the COMP pin, This is the compensation pin of the chip,How should I configure this pin?
Generally speaking, I think there are two compensation…
Part Number: TPS92520-Q1 Other Parts Discussed in Thread: TPS922052 Hi team,
I find lots of CC/CV BUCK coverters utilizes constant-on-time control (COT), while TPS92520 is featured with constant-off-time control(COT). Would you please help explain why…
Part Number: TPS92520-Q1 Other Parts Discussed in Thread: TPS92519-Q1 , TPS92643-Q1 Hello,
I would like to leave one channel left unconnected. With no SPI communications either. Is is enough to pull UDIM to ground in order to disable the output while…
Part Number: TPS92520-Q1 Hello Team, I found that a problem about use the TPS92682+TPS92520,TPS92682 is set consant voltage 50V,TPS92520 constant current is set 1.3A,when I change the output voltage from 4~40V, the output current will occur change too, …
Part Number: TPS92520-Q1 Hi team,
I have saw the thread and datasheet's bode plots as below. I'm curious about how to build the circuit to test the bode plots. could you please provide to me? thanks.

Part Number: TPS92520-Q1 Hello
The PWM frequency set internally in TPS92520 is abnormal. We use the combination of TPS92682 + TPS92520, with 2-phase boost and 6-phase buck. There is no problem using the default PWM frequency. When using 215Hz and the…
