LM25085A - 42V Constant On-Time PFET Buck Switching Controller
The LM25085A is a functional variant of the LM25085 COT PFET Buck Switching Controller.
The functional differences of the LM25085A are: The feedback reference voltage is 0.9V, the forced off-time after current limit detection is longer, and the soft-start time is shorter (1.8 ms).
The LM25085A is a
