HG2592 SIMPLE SWITCHER Power Converter 150 kHz 3A Step-Down Voltage Regulator
General Description
The HG25912 seriesofregulatorsaremonolithicintegrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version.
Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator.
The HG2592 seriesoperatesataswitchingfrequencyof 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.
