Part Number: LM51772EVM-HP Other Parts Discussed in Thread: LM51772 , , LM251772 Tool/software: Hi,
I am considering using the LM51772 as the basis of a li-ion battery charger, for a battery pack which only requires a constant current of approx 8A,…
Part Number: LM51772EVM-HP Other Parts Discussed in Thread: LM51772 , LM5177 we would like to ask if we can put two LM51772 boards at parallel to get higher power ?
we need 600W power output
Hi Nayef,
thank you for using the E2E forum.
Yes, it does.
Below screen shot was done on the LM51772EVM-HP (see there for details on the components used).
Discharge Config 0: set
Discharge Config 1: not set
Discharge Strength: 75mA
Best…
Part Number: USB2ANY Other Parts Discussed in Thread: LM51772EVM-HP , , LM51772 Tool/software: I'm pissed atm, I ordered the USB2ANY with my LM51772EVM-HP so I can directly test my use case without designing a prototype. I tried to connect everything…
Hello Juin,
The best practice for the sense resistor is a specifically produced sense resistor an example can be found on the EVM with R7: LM5176EVM-HP Evaluation board | TI.com
And even better is a resistor hat is wide and short. One example could…
Hi Jongyun,
yes, this is exactly the application case the LM51772 has been designed for.
For an easy start you can use the EVM: LM51772EVM-HP
Best regards,
Stefan
Hi Stefan,
Thank you for your support.
The conditions measured by the customer were those during normal use. VCC2 oscillation also occurs under the same conditions. Once VCC2 oscillates, it will not return to normal operation. That's why we measure…
Hi Siyang,
thank you for using the E2E forum.
So far we do not have a PSpice model for the LM51772.
Best would be to use the EVM (LM51772EVM-HP) for evaluation.
Would you have any special requirements for a simulation setup which can not be evaluated…
Part Number: LM51772 Tool/software: I am looking at connecting two of the LM51772EVM-HP evaluation boards in Parallel (Multiphase) operation and would appreciate some assistance. I have currently configured two separate evaluation boards in I2C mode …
Hello Stefan,
I am "the customer" :)
I'm currently testing with the LM51772EVM-HP and the average current limit control loop has some difficulties with the 47mF output capacitor. It oscillates with ca. 45 kHz, e.g. measurement from the start up: …
