Other Parts Discussed in Thread: TPS65251 Hi
I have done the calculation for the TPS65251 With three different O/P voltages as 3.7,3.3,1.8
I need to check this values we are having few doubts in the calculation of compensation circuit ?
Are the compensation…
Other Parts Discussed in Thread: TPS65251 , TPS65251-Q1 Hello,
My customer would like to know about R1/R2 shown on page 13 in the datasheet. It shows 40.2kOhm to improve efficiency for llight load, but it's not E24 parts. It also requires R2 > 47kohm…
Other Parts Discussed in Thread: TPS65279 , TPS65251 Hi all,
A customer has a question about the TPS65279 and features associated with its PGOOD and EN pins. Data related to the questions have been shown on datasheets for similar parts, but not on the 65279…
Other Parts Discussed in Thread: TPS65251 Hi team,
Here is a question from one of my customers seeking to better understand the TPS65251's internal operation and compensation:
1) I'm looking for a more detailed block diagram or any additional information…
Hi
Apologies for the delay in responding here.
The TPS65251 is a step down converter so that the output voltage will always be less than the input voltage so I don't understand how it is that you are getting 50V output.
The power loss in the resistor…
Hi Watkins,
Thanks for your response. Just few more queries:
1. BUCK1 can deliver peak currents of 3.5A Maximum right? Will this happen say when the BUCK2 and BUCK3 are in continuous loading condition of 2A?
2. Also can TPS65251 be used to generate 1…
Other Parts Discussed in Thread: TPS65251 I have two questions about the TPS65251:
1) What is the ramp up and ramp down time on the TPS65251 power outputs ( or definable min and max )? I see that I can set the soft-start time in the datasheet page 15…
Other Parts Discussed in Thread: TPS65251 dear Sir...
we had question to TPS65251's operation condition.
if we did disconnect the 1 Vin line,
it can good operation about remain 2 output...
Other Parts Discussed in Thread: TPS65251 , TPS65253 Hi ,
One of our customer is developing a hand held POS based on TPS65251 PMIC and rail are follows ........ customer is not getting the efficiency in Light load . how we have to increase the efficien…
Other Parts Discussed in Thread: TPS65251 I have an application for the TPS65251 in which I am generating 3.3V on Buck 1 and 1.8V and 1.2V on Buck 2 & 3. My power sequencing requirements are:
1.) 1.2V
2.) 1.8V & 3.3V
I noticed the datasheet…
