Other Parts Discussed in Thread: LM5146, CSD17304Q3, CSD17573Q5B, LM5145-Q1, LM25145, LM25148-Q1
I am using LM5146 for design, which requires input 12v and output 2v@10A. The reference design obtained by using webdesigner is shown in the following figure(the highside mos is CSD17304Q3,the lowhside mos is CSD17573Q5B):
Through simulation, it is found that the phase margin and gain margin are far beyond the recommended value. Is this normal?
Also enter the circuit parameters from webdesigner into quickstart, bode plot below:
It can be seen that the phase margin and gain margin calculated by quickstart differ greatly from that of webdesigner. May I ask which design I should use for reference?
Attached is the official quickstart program.
