Part Number: TPS40195 Hello,
I use this integrated for a 12V to 5V converter.
Problems encountered:
At pin 16 (HDRV) I have a constant voltage of 3V
At pin 14 (LDRV) I have a constant voltage of 4.4V
And the output voltage is not 5V, it is…
Part Number: TPS40195 Other Parts Discussed in Thread: LM25117 , LM5141 Hi Team,
I would like to find the solution which could meet below requirements.
1. Vin = 12V
2. Vout = 10.5V-8V
3. Iout = 10A
And I found that duty(max) is 87.5%. It…
Other Parts Discussed in Thread: TPS40195 Hi ,
we are using the TPS40195 with RT Resistor set for 0.8 x 600Khz and a SYNC signal of 600Khz without problems.
But now i need to answer the question what happens if the clock signal connected to SYNC is…
Ashok,
I apologize, I just saw this response as I was traveling when it was posted, and responded to your follow-on post.
While reducing BOOT to SW capcitor will improve the operation and reduce the likelihood of this failure, it is not as reliable…

Other Parts Discussed in Thread: TPS40195 Hi,
Now I'm trying to calculate the Ron of rectifier MOSFET by referring formula (23), but I’m not sure where 0.338W of Pcon came from. Please let me know.

Other Parts Discussed in Thread: TPS40195 Hello,
I would like to know about absolute maximum rating of LDRV pin.
LDRV pin ratings is "-0.3 to 6V"
But I can see the negative spike about -0.8V in the figure 18 at the datasheet page 14.
Is this…
Hi MC-san,
Thank you for your quick and detailed resonse!!
I could understand the purpose of adding this Rsw. And also TPS40195 does not care about it at low input voltage especially.
Best Regards,

Other Parts Discussed in Thread: TPS40195 , TPS40060 Hi Everyone,
Please let me know about resistor located between SW node and drain of LS FET in fig.24 on TPS40195 datasheet. I found the explanation for this Rsw in datasheet of TPS40060 and understood…
If the ILIM pin bias current range of 7 uA for min and 11uA for max is not related to the temperature compension
Per page 4 of the electrical specification table, the 7-11uA current source is specifically at Tj = 25C and does not include temperature…
