Part Number: LM251772EVM-PD Other Parts Discussed in Thread: LM251772 , , LM51772 Hi,
We are testing LM251772EVM-PD board as standalone mode (no I2C) but we couldn't acheive output voltage. Can this EVM or LM251772 IC works for standalone mode or will…
Part Number: LM251772EVM-PD Other Parts Discussed in Thread: LM251772 , USB2ANY , LM251772-Q1 Hi team,
My customers are evaluating the LM251772EVM-PD, currrently they are not connecting it with I2C, JP10 and JP11 are set with SCL and SDA both connection…
Hi Ishiwata,
I have used the LM251772EVM-PD with adding 440uF additional output Cap and made connection to feed in DTRK - no other changes.
You can find the schematic and BOM in the EVM users guide showing all components.
VIN: 24V / load: 0.2mS…
Hi Volodymyr,
the LM251772 is a spin of the LMN51772 which is targeted for USB-PD.
There you also can find some reference designs:

Darren,
I confirmed the request went through.
The EVM is available now, TPS26742-Q1 ICs will be available at the end of October.. I suggest ordering https://www.ti.com/tool/TPS26742EQ1EVM , then swapping 742-Q1 for 742E-Q1 on the PCB. You will also…
Hi Dmytro,
there are some reference designs already done with the LM251772 (a derivate of the LM51772 but more targeted to USB-PD)

Hi Aurora,
if you need to operate input voltage up to 20V and output voltage down to 20V you might need a Buck Boost to have a stable supply for that condition.
In that case please have a look a:

Hi Alex,
thank you for using the E2E forum.
In the LM251772EVM-PD Evaluation board is an implementation shown for the DRV1 pin to control a c-channel MOSFET.
In this case the intention is to disconnect the so that current from the output can not…
Hi Zhang,
not sure about the spec for this power supply.
With using the info i have found in the webench.pdf:
VinMin = 24.0V VinMax = 30.0V Vout = 48.0V Iout = 20.0A
It should be able to handle an output power of 960W.
If not an active cooling…
