Part Number: LM25116 Hi TI expert,
Now I want to use LM25116 to generate a negative voltage.
Total spec is that:
Vin: 12.6V
Vout: -13V
Iout: 3.5A~4A
As for inductor, I want to use SER1360-103KLB(Coilcraft), which is 10uH, Rated current 7A.
As for MOSFET…
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…
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
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.
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 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 What will happen to the power supply IC if it is operated beyond the minimum value of VCC_current_limit (TYP is not exceeded)?
Will it break? Or does it just continue to work even though it can't drive the MOSFET?
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…
