Part Number: LM5118 Hi TI experts...
I have a design with these parameters:
Vin = 12 V - 48 V
Vout = -12 V
Iout = 3 A
i want to put a inrush current circuit in my Vin, can you give me any recommendation about that.
Part Number: LM5118 Hello good morning I have a noise problem with the HO pin switching signal. The signal looks like this:
VIN = 24VDC.
VOUT = 12VDC.
switching frequency = 100 KHZ.
I don't have load for the output.
This is my circuit, I got it from…
Part Number: LM5118 Hi TI experts...
I have a design with these parameters:
Vin = 11 V - 48 V
Vout = 12 V
Iout = 5 A
f = 100 kHz
This is the circuit
these are my measure data:
I would like to raise my red dots above 70%, what do you recommend me to…
Hello Team,
We are using the LM5118 also , along with LMP8646 to limit current so that it behaves as a CC source. We will design the LM5118 for 54.6V with the current limit of 3A. So we expect the LM5118 to behave as CC mode during charging a battery…
Part Number: LM5118EVAL Other Parts Discussed in Thread: LM5118 Hi,
i have been working on this board (LM5118 Wide Voltage Range Buck-Boost Controller). I have a question please!
and my question is: can it be posible to implement a reverse polarity on…
hi stefan,
yes it looks like everything is clear for me now.
im now working on the final board. this is my newest design please feel free is you see any foults
Part Number: LM5118-Q1 Hi, Please provide the Functional Safety FIT Rate and FMD manual of LM5118-Q1. Functional Safety Information is required for functional safety FMEDA calculations. Thank you very much!
Hi Haroon,
Thanks for detailed waveforms, the result is confirmed that LM5118 cannot be used as pure Buck topology. And from the waveforms, it can be seen that SS pin didn't restart, COMP is high clamped. It seems that some protection is triggered.…
Part Number: LM5118 Other Parts Discussed in Thread: LMP8646 Hello Team,
So we wanted to use the LM5118 to design a CC and CV mode buck-boost charger to charge a battery.The input is 48V,6.6A from DC adapter and the output would be 54.6V with a current…
Hello Bhanu,
As we did not hear back from you, I expect that your issue is solved and I close this thread. Please post below if you have further question or start a new thread.
Best regards, Brigitte
