Part Number: LM51772 Tool/software: Dear
Why is there a limitation on the maximum output voltage? Shouldn't the allowable output voltage not be restricted by the IC once the MOSFET is external?
The current design uses the MPQ4284. I've noticed that…
Part Number: LM51772 Tool/software: I have configured a circuit using LM51772 as shown below to obtain an output voltage of 24V/5A with an input voltage of 18~48V.
I confirmed that the output voltage is maintained at 24V when the input voltage is 24V…
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: 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…
