Part Number: LM51772EVM-HP Tool/software: Are the schematic and/or layout files available for this board ? This uses the
LM51772RHAR
55V wide VIN four-switch buck-boost controller with I2C interface that has
a 55V max on both Vin and Vout using an external…
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
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…
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…
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…
Hi Joscha,
the LM51772 will fit very well but input range is limited to 55V. The LM5177 can be used as well which will also allow higher input voltages but for that device the output voltage control needs to be done externally.
Due the the large about…
