Other Parts Discussed in Thread: LM25116, TPS40170
Hi ,
I Have used TPS40170QRGYRQ1 in one my new prototype design where the i/p is between 5V to 30V and o/p required is 3.3V @15A (max), 8 A(typical), 4A (min).
I have referred the design generated by the TI's Webench tool. Reference design and actual design schematics are attached herewith.
When powering the board with 12V supply, the o/p seen on the 3.3V is not stable and shows lot of switching from 2.6 V to 3.8V. i have taken the waveforms at inductor switching side, o/p Cap which are attached herewith.
Please help me in getting this issue resolved.
