Regulator
• Efficient Preregulator for Linear Regulators
• On-Card Switching Regulators
• Positive-to-Negative Converter (Buck-Boost)
The LM2576 series of regulators are monolithic
integrated circuits that provide all the active functions
for a step-down (buck) switching regulator, capable of
driving 3-A load with excellent line and load
regulation. These devices are available in fixed output
voltages of 3.3 V, 5 V, 12 V, 15 V, and an adjustable
output version.
Requiring a minimum number of external
components, these regulators are simple to use and
include fault protection and a fixed-frequency
oscillator
