Part Number: LM51772 Tool/software: Dear Sirs and Madams,
The datasheet for LM51772 describes VTH+(PG) and VTH-(PG), but does not list these specs.
When using external feedback resistors, I think the internal reference is 1V, Could you priovide us how…
Part Number: LM51772 Tool/software: Hi TI Experts
We use LM51227 in wireless power charger in auto.
The datasheet described the Vo can dynamical progarming via I2C from:
-3.3V up to48V in20 mV steps
-1V up to 24V in 10mV steps.
The question is:
If we…
Part Number: LM51772 Tool/software: Howdy! Two questions for you:
What is needed to enable ILIMCOMP? In figure 7-22, we are curious which passives are needed and which registers are required to enable ILIM detection
Similar to question above, using…
Part Number: LM51772 Tool/software: Hi Sir
I have two question when design in 9-36Vin 12Vo 12~18A.

Part Number: LM51772 Other Parts Discussed in Thread: LM251772 , , AMC1200 , LM5177 , LM51770 Tool/software: Dear experts,
is it possible to use the USB-PD controller LM51772/LM251772 with a full bridge transformer, instead of the 4-switch buck-boost configuration…
Part Number: LM51772 Tool/software: Hi
When testing LM51772, it was found that the 65W PD DC-DC set has a fixed frequency sound when VOUT is 20V and VIN is about 11.5V~12V. At this time, the measured VIN voltage ripple will be slightly larger. Which…
Part Number: LM51772 Tool/software: Dear forum,
we tried to build a DC/DC converter with an LM51772. This is intended to provide a constant voltage (28.4 V) and an adjustable current (per I2C) for charging a battery, max 15 A. The input voltage is between…
Part Number: LM51772 Tool/software: Hi Team,
Could you reply to my questions below? Thanks!
Design Brief: The IIC Buck Boost raises the battery voltage to between 0 and 20+V (in steps) and then supplies it to a push-pull stage. This stage, through transformer…
Hi Stefan,
I was in the external lab yesterday and the results are quite good. I used the internal feedback and injected the signal on R41.
In general the simulation does not match the measurement at all, what I don't really understand. But we already…
Part Number: LM51772 Tool/software: Hi TI expert team,
has anyone ever operated the LM51772 with low voltage GaN HEMTs as external MOSFETs? If so, at what switching frequency and what input and output values?
Because I would like to try this, but the…
