LM25085A
42V Constant On-Time PFET Buck Switching Controller with 0.
9V Reference
General Description
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 high efficiency PFET switching
regulator controller that can be used to quickly and easily develop a small, efficient buck
regulator for a wide range of applications.
This high voltage controller con...
