Part Number: TPS552892-Q1 Other Parts Discussed in Thread: TPS55289 Dear TI team,
I have some issues with a circuit that was assigned to me: the circuit was previously designed with a tps55289 by mistake, as the application wasn't intended to be controlled…
Hi Bryce,
Good day,
Thanks for the clarifications.
Could you please clarify the following queries as well?

Part Number: TPS552892-Q1 Other Parts Discussed in Thread: TPS552892 Hi Team,
The TPS552892 has a average current limit, I got a question from my customer for how long is considered for this averaging (ex: how long do we have to be above 7-9A to trip…
Part Number: TPS552892-Q1 Other Parts Discussed in Thread: TPS552892 Hi Team,
I'd like to ask you about thermal issue of this device. Customer is verifying it on their board, but there is a thermal issue on this device. Please check the attached schematic…
Part Number: TPS552892-Q1 Hello team,
My customer is doing the test as below:
They use the external supply to VCC pin, EXTVCC pull low. But at real test, they disconnect VCC pin to 5V supply.
Here is their test result:
VCC would have a small raise…

Dear team,
I am learning about TPS552892-Q1, and there are two points that are confusing：
1. How does the boot-strap capacitance of TPS552892-Q1 work? In the picture, if high side buck FET is on, the voltage of red point…
Part Number: TPS552892-Q1 Dear team:
Could you kindly help me with a few problems about compensation loop:
1. Isink、source、Vcclph、Vcclpl： What do these parameters mean？Dose these parameters limit loop compensation parameter selection？
2. The…
