Part Number: TPS65262-1 I am using the TPS65262-1 to deliver the following voltages
Buck 1 = 12V input, 5V output
Buck 2 = 5V input, 3V3 output (5V is supplied by output of buck 1)
Buck 3 = 5V input, 1V2 output (5V is supplied by output of buck 1)

Hi support team.
In the May 2023 datasheet, the recommended capacitor for V7V of the following models have been changed from 1-μF to 10-μF.
TPS6…
Hi Darin,
Thanks for your feedback. You are correct. TPS65262-1 and TPS65262-2 are almost similar except LDOs and mode setting. This setting can also work for TPS65262-2.

Other Parts Discussed in Thread: TPS65262 , TPS65262-1 I have a design using the TPS65262-1. My design is identical to the TPS65262 eval board ( http://www.ti.com/tool/tps65262evm-619 )with the exception that the voltage output for the first switch mode…
Hi Cameron,
For the EVM bench test results of two LDOs parallel, please kindly see feedback shown below:
(1) As you can see from above EVM schematic, both LOUT1 and LOUT2 are set as 5Vout. Connect LVIN1 and LVIN2, connect output of LDO1 and output of…
Other Parts Discussed in Thread: TPS65262 , TPS65262-1 What's the availability of the TPS65262 and TPS65262-1? I don't find either of these parts available in distribution.
Are there any efficiency curves available for 3.3V, 2.5V and 1.2V outputs…
Hello again Lucia,
Another TPS65262 failed today in our product with the product power supply at -45C on the 12th cold power cycle. This time the 5V circuit (Buck 1) failed. The failure mode for both 3.3V/5V circuits (Buck1 on two different devices in…
Hi Jeff
Sorry for misleading, you are right , we got the same phenomenon that the situation will be better with PFM enable. Now customer's configuration is enable PFM. and open ADC to monitor will increase the power consumption of system. they need …
Part Number: TPS65262 Hi team,
Is it OK to leave the mode-pin of TPS65262/ TPS65262-1 floating?
If it is OK, would it be the same as pulled high?
If it is not OK, what would be the expected behavior?
Best regards,
Kurumi
