The LM2596 series of regulators are monolithic integrated
circuits ideally suited for easy and convenient design of a
step-down switching regualtor(buck converter).
All circuits of this series are capable of driving a 3.0A load
with excellent line and load regulation. These devices are
available in fixed output voltages of 3.3V, 5.0V,12V, 15V,
and an adjustable output version.
These regulatiors were designed to minimize the number of externalcomponents to simplify the
power supply design. Standard series of inductors optimized for use with the LM2576 are offered
by several different inductor manufacturers.
Since the LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in
comparison with popular three-terminal limear reguators, especially with higher input voltages.
