Part Number: LM25119Q When the measured current of the load after driving with 4.5V is 0.8A to 1.2A-2A, the voltage will be pulled down to 0.9V-1V and then restored. In the above figure, there is a CCAMP capacitor that has been changed to 4.7nF without…
Part Number: LM25119Q Hi
I am trying to simulate LM25119Q in an Interleaved topology.
I have used the Transient simulation circuit I downloaded from the website. I connected the circuit according to Webench suggestion for 12V input 5V/25A output.
But…

Part Number: LM25119Q Other Parts Discussed in Thread: LM25119 Dear TI Experts,
I am now using LM25119 and find a problem needs your suggestion:
Input 12V output 5V ,but their is no output now~
I check my layout and find that the thermal pad of LM25119…
Part Number: LM25119Q Other Parts Discussed in Thread: PMP20659 Dear Team,
For the LM25119Q reference design, can the BJT 2DB1694-7 used be replaced by MMSTA56Q?

Part Number: LM25119Q Dears:
Could you kindly help to check the schematic?
Since there is no output of 5V, and there is no signal testing Nmos' G pot and S pot.
There is no voltage testing FB PIN.
How is the state of PIN31 and PIN32?
Pls. give some…
Part Number: LM25119Q Dear Masters,

Part Number: LM25119Q Dear, Sir.
My customer are examining the adaptive dead-time cotrol on fail-safe-wise point of view.
Datasheet described on
"The LO and HO outputs are controlled with an adaptive dead-time methodology which insures that both outp…
Part Number: LM25119Q Hello Team,
Do we have a min/max range for the minimum on time parameter in the LM25119-Q1 datasheet? The typical value is 100ns, but I need to know how much higher the maximum number is to determine the max switching frequency I…
Part Number: LM25119Q Dear, Sir.
My customer is considering to change fSW 130kHz <=> 300kHz under the operation.
It is expected to reduce the influence of minimum On-time to set at lower fSW.
1. I would like to know that such usage will be no…
