Description
General part information
LM2590HV Series
The LM2590HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3-V, 5-V, and an adjustable output version.
This series of switching regulators is similar to the LM2591HV with additional supervisory and control features.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, improved line and load specifications, fixed-frequency oscillator,Shutdown/Soft-start, output error flag and flag delay.
