LM25011
42V, 2A Constant On-Time Switching
Regulator with Adjustable Current Limit
General Description
The LM25011 Constant On-time Step-Down Switching
Regulator features all the functions needed to implement a low cost, efficient, buck bias
regulator capable of supplying up to 2A of load current.
This high voltage
regulator contains an NChannel Buck switch, a startup
regulator, current limit detection, and internal ripple control.
The constant on-time regulation principle requires no loop compensation, results in fast load transient response, and simplifies circuit impleme...
