Part Number: TPS61178 Tool/software: Parameters of my design: Vin=10-16V, Vout=19V, Iout max =1,6A.
First question: is the T SHORT parameter specified somewhere? It is only mentioned in section 9.2.4.4.3 of the DS and it states it is 30us. Is this value…

Part Number: LMR51440 Other Parts Discussed in Thread: LMR51430 Tool/software: Dear Specialists,
My customer is considering LMR51440 and LMR51430.
They have a question about the Vf of low side FET and rise/fall time of the FET.
I would be grateful if…
Hi I R,
I am sorry to hear the efficiency and stability issues did not improve. The burst switching could also be the regular light load behavior. If the minimum on-time gets too low, the device will switch in bursts and the stops for a longer period of…
Part Number: TPS55288 Other Parts Discussed in Thread: CSD13202Q2 , TPS55289 Tool/software: Hello, I have been attempting to change the switching frequency for the TPS55288 by changing the resistor for the switching frequency on pin FSW. Ideally, I was…
Jass,
The forward voltage drop of the diode in the forward direction would be what you are looking for. For the case of the BAV199, it looks like:
So at the worst case scenario of around -40C and a lower operating current, you should be sufficiently…
