Part Number: TPS65261 Hi,
The datasheet recommends a 47nF capacitor between LX and BST pins. My customer is using a 100nF capacitor here.
Could you please tell me what the min/max range for this capacitor value is?
Thank you,
Michael Rosa
Part Number: TPS65261 Hi,
We are using the TPS65261 as a power converter in our inspection camera design. On the first cut of the board, there were absolutely no issues with the part. There has never been a failure. Now on the next board revision, with…
Part Number: TPS65261 Hello,
The startup characteristic using an external capacitor on the enable pins seems well defined based on the internal current sources. My question pertains to the source of the pull-up currents. In the block diagram there is…
Part Number: TPS65261
Dear Sirs,
We bought TPS65261-1RHBR from TI (Order No.:T01253074)
Yesterday our customer told us that there are 4% of the 12V power supply pins are short-circuited after a period of aging of TPS65261-1RHBR. They do not know why this problem happen…
Part Number: TPS65261 Hi Technical Support Administrator,
Could you please advise me what are the major difference in between TPS65261-1RHBR and TPS65261-RHBR?
Thanks,
Daniel
Part Number: TPS65261 Other Parts Discussed in Thread: TPS65263 Hi Team,
Do we have a design calculator tool for this device? Alternatively, do we have a general compensation optimizer for transconductance buck controllers?
Thank you, Delaney
Part Number: TPS65261 Hi team,
Please let me confirm my understanding of (16) & (17). Is the my understanding as below correct?
The output capacitance calculated by (16) is the min value for the good transient response.
The output capacitance calculated…
Part Number: TPS65261-1 Hi Expert,
My customer found the issue about Lx pin negative voltage ringing. (minimum around -2V)
Zoom-in
Absolute max of Lx pin : -1V to 20V
This waveform is reached negative side(-2V)
Is it any problem?
Also, Datasheet is…
Part Number: TPS65261-1 Other Parts Discussed in Thread: AMC3301 , TPS65261 , TPS65263 Hello,
I'm a relative newbie to using these devices and wanted to configure it originally for 1.5V, 3V3 and 5V, some way into the design, we ditched the 1.5V so are only…
