Regulator Efficient Preregulator for Linear Regulators On-Card Switching Regulators Positive-to-Negative Convertor Description
The LM2594xx seriesof regulators are monolithic
integrated circuits that provideall the active functions
fora step-down (buck) switching regulator, capableof
drivinga 0.5-A load with excellent line and load
regulation. These devices are availablein fixed output
voltagesof 3.3V,5V,12V, and an adjustable output
version, and are packagedina 8-pin PDIP anda8-
pin surface-mount SOIC package.
Requiring a minimum number of external
components, these regulators are simpleto use and
feature internal frequency compensation,a fixed-
frequency oscillator, and improved line and load
regulation specifications.
The LM2594xx series operates at a switching
frequency of 150-kHz, thus allowing smaller-sized
filter components than what would be needed with
lower-frequency switching regulators. Becauseofits
high efficiency, the copper traces on the printed-
circuit board are normally the only heat sinking
needed.
