LM2674 SIMPLE SWITCHER Power Converter High Efficiency 500 mA Step-Down Voltage Regulator September 1998 LM2674 SIMPLE SWITCHER ® Power Converter High Efficiency 500 mA Step-Down Voltage Regulator General Description The LM2674 series of regulators are monolithic integrated circuits built with a LMDMOS process. These regulators provide all the active functions for a step-down (buck) switching regulator, capable of driving a 500 mA load current with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5.0V, 12V, and an adjustable output version. Requiring a minimum number of external ponents, these regulators are simple to use and include...
