If you do not need automotive grade, TPS54060 is a possibility. If you need automotive grade, you can look at TPS57160-Q1. It is pin compatible but may need a different compensation.
Other Parts Discussed in Thread: TPS57160-Q1 Dear supprt member
I have one question about operation of TPS57160-Q1.
My customer performed BOOT-Vin short test of TPS57160-Q1 and got attached waveform.
Could you teach mechanism of this operation?…

In a custom design based on the RM57L843 MCU, I have designed the following power…
Other Parts Discussed in Thread: TPS57160-Q1 Hi ,
I would like to know output voltage of TPS57160-Q1 during input voltage is fluctuating.
The input voltage is moving by triangular at 400kHz , then a switching frequency is 2.2MHz.
In this case…
Hi Dmitri,
The TPS65381A-Q1 is very scalable on the VDD1 core supply since the integrated rail is an LDO controller with independent voltage monitoring (VMON). Attached is a PDF showing how to use an external DCDC for the core rail supply instead of…
Hi Saravanakumar,
I do not think you fully understood one of the earlier posts. The VDD1_SENSE pin of the TPS65381A-Q1 is used for two purposes: VDD1 regulation loop feedback (sense) and VDD1 voltage monitoring (VMON) or the independent voltage monitoring…
Hi Nakai-san,
A1: Yes, the TPS65381A-Q1 can be used with all TMS570 devices, however as you noted the more recent, higher performance devices may require more core current than the VDD1 LDO controller can provide or even a cascaded DCDC from VDD6 to…
Hello,
Due to thermal considerations, regulating from 24V to 5V at 1 A is almost always done with a switching DCDC (buck) regulator. TI has many automotive qualified devices in our buck portfolio. Generally to avoid EMI issues the switching frequency…
Hi Stomp,
Thank you for your question.
Indeed, thermal design considerations when using a 24V input supply is of most concern. The TPS65381A-Q1 includes a pre-regulator from input to 6V and then downstream LDOs with integrated FETs for…
1. What is the max. threshold value of TPS3808G50? Here is the calculation:
VIT (Typ) = 4,65V Tolerance = +/-2% (overall) => VIT (max) = 4,743V
Hysteresis (max) = 2,5%VIT => threshold value (max) = VIT(max) + 2,5%VIT(max) = 4,743V + 2,5% = 4,862V…
