Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM25143-Q1 Our circuit design is as follows:
Test the output waveform of the power supply and find that the output has a step with a duration of 610us.
In addition, we measured the GATE waveforms…
Hi Kygo,
The ICs are effectvely the same with two pins that are different (RT and MODE replace OSC and ILSET). The LM5143-Q1 is generally higher performance, and the LM25143-Q1 42V version will release later this month.

Hi Fred,
Please use the LM25149 quickstart calculator to assist with component selection and review power losses - the file can be downloaded from the product folder. Depending on the Vin, Vout, Fsw and max Ta, you may need paralleled FETs. However,…
