LM2675 series regulators, They are monolithic integrated DC-DC converter circuits built with an LMDMOS process. These regulators provide all active functions for a buck switching regulator capable of driving a 1-A load current with excellent line and load regulation.
Requiring a minimum number of external components, these regulators are easy to use and feature patented internal frequency compensation and fixed frequency oscillator.
The LM2675 series operates at a switching frequency of 260 kHz, so Allows smaller sized filter components than needed in lower frequency switching regulators.
