LM25116_buck_controller_datasheet

M25116 Wide-Range Synchronous Buck Controller
Wide operating range (up to 42 V)
Programmable output from 1.215 V to 36V
Free-run or synchronous operation to 1 MHz
The LM25116 is a synchronous buck controller intended for step-down regulator applications from a high voltage or widely varying input supply. The control method is based upon current mode control using an emulated current ramp.
