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…
Part Number: TPS92520-Q1 Hi team,
Could you please help me understand why operating at higher input voltage, the bootstrap voltage would drop below UVLO?
And Why after high-side current limit is triggered and then the low-side current limit is triggered…
Part Number: TPS92520-Q1 Hello, What is the tolerance of switching frequency? How to calculate this? For example, if CHxTON=000111, typ switching frequency is 437kHz, and how to calculate the min and max switching frequency?
Thanks.
Part Number: TPS92520-Q1 Hello expert,
A slope compensation should be added in case of duty cycle greater than or equal to 50%, to avoid subharmonic oscillations.
So is there slope compensation in this device? I can't find any information from the…
Part Number: TPS92520-Q1 Hello expert,
Below is the customer requirement. How to understand this? Does it mean we should set the PWM dimming frequency no less than 1000Hz?
Part Number: TPS92520-Q1 Hello expert:
To improve the output current accuracy in low current application(0.1A for example). I want to increase the Rcs value(R1303) and what is the limit? Is 1.5R OK? Then will much higher than the Rdc of the power i…
Part Number: TPS92520-Q1 Hello expert,
I found in the datasheet that Absolute Maximum Junction temperature is 150C, but the Thermal shutdown threshold is 175C(Typ), so what happened if Tj higher than 150C but lower than 175C? In my protect MCU read the…
