Part Number: LM51772 Hi sir,
Customer use CPU to control LM51772 via I2C.
Their first time to use, so that they are asking if there's any SW control guide, flow chart, initial code...etc.
Thanks a lot!
Part Number: LM51772 Good evening, We built a buck-boost circuit using the LM51772 integrated circuit, the schematic of which is attached. The circuit is very similar to the one on the EVM, with some simplifications, so only a few basic features are used…
Part Number: LM51772 Other Parts Discussed in Thread: LM5176 Hi ,
We has new project use LM51772 and fine tune the efficiency on EVT PCB.
Please see as below test result.
1)The F=300KHz ; SLOPE=2.5 efficiency is lower rhan F=480KHz ; SLOPE=1.5…
Part Number: LM51772 hello team,
I am using the LM51772 in boost mode to supply a GaN power amplifier where sequencing requires Vd(powered by the LM51772) to reach 0V before removing other power rails to avoid excessive drain current and overheating…
Part Number: LM51772 Other Parts Discussed in Thread: LM5177 Greetings,
Hope this finds you well. We are developing a I2C programmable supply with LM51772 and would like to validate our design. Input can be 24 to 48V and output from 1V to 45V. Our application…
Part Number: LM51772 Good morning,
I have developed a custom board based on the LM51772, and I am experiencing an unexpected temperature rise of the IC. The device reaches approximately 80ºC while delivering only 50 W of output power, which should not…
Part Number: LM51772 The input voltage range is 27V to 29V.
The expected maximum load current is up to 2A.
The desired output voltage is adjustable from 20V to 40V using I2C control.
Part Number: LM51772 Hi,
Plesae advise if LM51772 can support the more than 3pcs Parallel design that the circuit can support more redundant spec. in our project, thanks.
Part Number: LM51772 The LM51772 is working properly when 1st started. I disable the CONV_EN and CONV_EN2 control bits to turn OFF regulator and Vout turns OFF as expected.
However when I re-enable the CONV_EN and CONV_EN2 bits the Vout is not enabled…
Part Number: LM51772
In one of our projects, we used the LM51772RHAR to make a stable output voltage that can be changed by the I2C interface.
We did test with the device, and the output voltage can be set by I2C without problems.
But we also…
