Part Number: LM26480-Q1 Hello,
I am currently designing power circuitry using LM26480-Q1 and I have question regarding the GND separation for this chip.
As this chip has pin for core ground (GND_C) , LDO ground (GND_L) , and switching GND (GND_SW1…
Part Number: LM26480-Q1 Hi TI team,
I have some questions regarding the LM26480-Q1 :
- What is the maximal current that can support the open drain logic output nPOR when it is pulled to ground? it is not specified in the datasheet.
-I use this…

Part Number: LM26480-Q1 Customer's safety team came back to me with some technical questions as shown below :
- we would like to measure/verify threshold levels for UV detection at Buck1 and buck2 output. Moreover in data sheet there’re only typical…
Hello Brian,
thank you for your support.
My customer found the large overshoot and undershoot at switching waveform.
therefore, they have been concerned that LM26480-Q1 may be broken by overshoot and undershoot.
the undershoot peak voltage was…
Part Number: LM26480-Q1 Other Parts Discussed in Thread: LM26480 , TINA-TI I downloaded the TINA-TI Spice model of LM26480. However, couldn't get the AC Analysis working using LM26480_BUCK1 TRANSIENT MODEL. Any help on this is highly appreciated.

Part Number: LM26480-Q1 Hi Team,
My customer is interested in LM26480-Q1
The required output sequence is below;
Vin 3.3V -> 1.8V (Back1)
Vin 3.3V -> 1.1 (Back2)
LDO1 3.3 -> 2.8
NPOR (1.8V)
Under the above condition, can ENSW2 be enabled…
Hi Dexter,
For TPS65265 part, there are some comments below:
1. Suggest to add a 1uF or 0.1uF cap to PVIN and GND. And place the cap as close as possible to PVIN on layout.
2. For Buck1 and 2, 4.7uH inductance (L6 and L7) is okay for your application…
Part Number: LM26480-Q1 Dear support team
Could you provide thermal data of below condition?
