LM25085A controller equivalent, 42v constant on-time pfet buck switching controller.
1
*2 Wide 4.5V to 42V Input Voltage Range
* Adjustable Current Limit using RDS(ON) or a
Current Sense Resistor
* Programmable Switching Frequency to 1MHz
.
This high voltage controller contains a PFET gate driver and a high voltage bias regulator which operates over a wide 4.
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-.
