Other Parts Discussed in Thread: PMP20021, PMP9700
Dear Sir,
DEMB(PIN17): floating is enable diode emulation mode and low side MOSFET latch-off. right ?
-> that mean LM25119 into like as non-sync. Buck converter during output light load.
My customer try modify EVM make a 2phase output, output load transient H -> L(5A ->0A) as previously waveform SW have stop condition(make have overshoot issue).
But when we put DEMB connect to VCC1 output transient waveform(SW) didn't have stop & output voltage transient waveform OK. It is correct behavior?
I saw TI design PMP20021/ PMP9700 the DEMB is connect to VCC.
Thanks!
Steven
