Part Number: LM5143-Q1 Dear TI
Connect MODE pin to VDDA for interleaved signal-output operation,
when in signal-output operation,how to measure Bode Plot?
where to place the series resistor?
thanks!
Part Number: LM5143-Q1 Other Parts Discussed in Thread: LM5143 Hi,
we are using two LM5143-Q1 Buck with Dual output mode-12V nom ip voltage and 12A current each, so 12+12=25A per Buck and another 25A for another buck.
now we are planning to use 25A+25A…
