Part Number: TPS65251 Hi Team,
Could you show the difference between TPS65251 and TPS65251-x, as well as difference between TPS65251-1, TPS65251-2 and TPS65251-3?
I looked at the datasheet but didn't find...
thanks a lot.
Best regards,

Part Number: TPS65251 Hi I'm using the TPS65251 to create 3 voltage rails and have a design very similar to the reference design in the datasheet and the reference device.
When powering on the board with no load I was getting the correct voltages on…
Part Number: TPS65251 As per our requirement, we are using two outputs of TPS65251. Buck 1 : 3.3V & Buck 2 : 1.2V.and PGOOD for power status in our design.
Buck 3 is properly disabled by pulling low to the EN3 pin,
Even though we are disabling Buck…
Hi, Jordan
I review your schematic, it is okay, but layout is bad.
I think the issue is caused by bad layout, suggest place 30ea VIAs at thermal pad.
I attached a layout guideline for your reference.

Part Number: TPS65251 Hi,
My input voltage is 12V, O/p of buck1 = 3.3V, Buck2 = 2.5V, Buck3 = 1.8V.
1. During the bringup, the EN of Buck1 is toggling i have checked the input ripple which is around 500mV.
2. When i am checking the datasheet there where…
Part Number: TPS65251 Hi, Team
My communication customer is using TPS65251-3 in their small cell products. They find the output voltage will drop during startup, if the outpu voltage is set to > 3.5V.
Here is customer schematic. The CH3 of TPS65251…
Hi, Gabriel 1. The IC has the discharge time enable pins(tD) function. (see the page7 of datasheet.) It can assure the EN cap fully discharged. The TPS65251-1 is similar with TPS65250, they have same IP. In the page13 of TPS65251-1, there is time…
