Other Parts Discussed in Thread: LM5001, LM3488, LM3481, TPS54140A
Hi Team,
I'm currently looking at using the TPS54040A for a Buck-Boost application with the following parameters:
Vin: 13 - 17V
Vout: 15V +/- 5%
Vripple: 150mVp-p
Iout Max: 250mA
However, there is no Max current limit threshold in the datasheet - only 0.94A typical. Is this an error in the datasheet? Is there data on what the max current limit would be?
Also, my application with be running in high temp environments and I was wondering if there is any data how the current limit varies over temp (preferable from -40 to 150C) since it is only speced at Tj = 25C.
Thanks,
Hayden
