PRODUCT DESCRIPTION/SPECIFICATIONS
PRODUCT DESCRIPTION:
The LM2596 regulator is monolithic integrated circuit ideally suited
for easy and convenient design of a step−down switching regulator
(buck converter). It is capable of driving a 3.0 A load with excellent line and load regulation. This device is available in adjustable output
version and it is internally compensated to minimize the number of
external components to simplify the power supply design.
Since LM2596 converter is a switch−mode power supply, its
efficiency is significantly higher in comparison with popular
three−terminal linear regulators, especially with higher input voltages.
The LM2596 operates at a switching frequency of 150 kHz thus
allowing smaller sized filter components than what would be needed
with lower frequency switching regulators. Available in a standard
5−lead TO−220 package with several different lead bend options, and
D2PAK surface mount package.
The other features include a guaranteed 4% tolerance on output
voltage within specified input voltages and output load conditions, and
15% on the oscillator frequency. External shutdown is included,
featuring 80 A (typical) standby current. Self protection features
include switch cycle−by−cycle current limit for the output switch, as
well as thermal shutdown for complete protection under fault
conditions.
