i do a simulation with LT8609. but there is some big spike noise about 10Vp-p on Vin, when Cin has 0.6nH of ESL.
and , there is no problem in LT8609A with same simulation.
is there any Bug in LT8609 spice model?
LT8609 has faster turn-on/turn-off edge than LT8609A. So the noise is higher than LT8609A.
