Part Number: TPS65251 Hi
Could you tell me the EN delay of TPS65251RHAR.
After Hi level voltage is applied externally to EN (1/2/3), how long does it take for the output voltage to start to rise.
Please tell me Min / TYP / Max.
Also, if there is a time…

Other Parts Discussed in Thread: TPS65251 Hi all Would you mind if we ask TPS65251?
The datasheet shows followings; -The PGOOD pin is pulled low when any buck converter is pulled below 85% of the nominal output voltage. -The PGOOD is pulled up when all three…
Other Parts Discussed in Thread: TPS65251 , LM3880 Hi,
I will use LM3880 for power sequencing of all 3 outputs of TPS65251. I also need to use PGOOD output of TPS65251 to reset my CPU. According to TPS65251 datasheet :
"The PGOOD pin is pulled low when…
Other Parts Discussed in Thread: TPS65251 On the TPS65251 can I run each separate Buck converter off of a different voltage than the supply voltage? On this IC there are 3 pins labeled Vin... then each converter has an input voltage too: Vin1, Vin2,…
Other Parts Discussed in Thread: TPS65251 , TPS652510 , TPS65261 I am trying to use Webench with a PMIC. I would like to use TPS65251 but can only find TPS652510. I have 3 outputs: 1.2V, 1.8v, and 3.3V. I would like to run the switching frequency at 1Mhz…
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 , TPS65251EVM I purchased a TPS65251EVM eval board for verification of this part for a new design, but I’m not measuring efficiencies anywhere near what’s show in the TPS65251 datasheet.
For example…
Other Parts Discussed in Thread: TPS65251 Hi,
I am using a TPS65251 device for generating 3 different supply voltages.
i.e. Buchk1 - 3V3, Buck2 - 1V1 and Buck3 - 5V
TPS65251 has single POWERGOOD pin which goes low if any of the buck's output is lower then…
