LM2591HV SIMPLE SWITCHER Power Converter 150 kHz 1A Step-Down Voltage Regulator July 2003 LM2591HV SIMPLE SWITCHER ® Power Converter 150 kHz 1A Step-Down Voltage Regulator General Description The LM2591HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, and an adjustable output version. This series of switching regulators is similar to the LM2590HV, but without some of the supervisory and performance Features of the latter. Requiring a minimum number of external...
