Part Number: LM25116 Tool/software: ①In 8.2.2.6 of the datasheet, it says that the input ripple current is IRMS > IOUT / 2, but is it okay to estimate it at a value close to IOUT / 2?
Conditions: Vin 24V Vout 17V~10V Iout 11A, 4A (2 circuit design)

Part Number: LM25119 Tool/software: Dear TI,
I am not sure is this is allowed to use NMOS RDSon as the shunt resistor?
If this is possible what filtering RC should be used?
Bests,

Part Number: LM25116 Other Parts Discussed in Thread: LM5116 We used the LM25116 IC for designing a buck converter which steps down the voltage from the range of 18V - 30V to 12V.
We used a 25mOhm resistor as the shunt and according to the datasheet values…
Part Number: LM25116 I am not able to simulate my design which use LM25116 IC. I just wanted to know whether LM25116 can be simulate on PSpice or not and if not then which software I can used to simulate my LM 25116 design.
I am closing this thread since I have not heard from you for sometime. If you are still trying to resolve the issue, please feel free to open a new thread. Thanks - EL
Hello nnn
In buck converters, ton = VOUT/VIN/Fsw if no loss.
When the VOUT is grounded, the output current will be limited to 'Short Circuit Current'

Part Number: LM25116 Running the test transient simulation in the PSPICE for TI environment does not show the lower MOS transistor switching. It is continuously off. There exists no synchronous rectifying. I tried also in a heavy load situation. Is the…
Part Number: LM25116 Dear Sir/Madam,
I have built new prototype boards with the LM25116. This acts to convert the main input power (8 - 32 V) to a regulated 5V supply for my board. Max current drawn is a theoretical 1.2 Amps but is usually closer to 0…
Part Number: LM25116 Other Parts Discussed in Thread: LM5116 I created a power supply that can vary the output voltage by combining a feedback resistor with a digital potentiometer. Output voltage can be varied to 12V, 14V, 16V, and 17V. When there is no…
Part Number: LM25116 Other Parts Discussed in Thread: LM5117 , , LM5148 Hi,
Can we use LM25116MH/NOPB IC in CC/CV mode?
For my design I need both current and voltage controlled IC like LM5117. Is this LM25116MH/NOPB suitable?
What is different between LM25116…
