Hi thanks for kindly guide. it's very helpfull to me.
but I check result is,
For 2phase, 1single out
1) if R3 (V1_Vout line to FB1 pin) open & R2(GND line FB to FB1pin) short = in operating SW V1 is latch-up as not enabled. so V1 doens't work Switching.
eventhough Iload 3[A] (V0, V1 each 1.5[A]) condition, doesn't work V1 switching (only V0 switching)
2) just R3 short & R2 open
in this condition (@3[A] I load, each channel 1.5[A}) it works as 2phase operating.
I can't understanding this situation.
please re-check 2phase 1out operating condition.
3) please let me know how to use No-use SW enable,
I wanna know LP87330Q1 EVM BD operating without SW enable, For exaple, just only
connect Vin, and then it can operate PFM -> PWM and Phase add and shedding operating.
if it can, what condition operationg? Vout level ?
