General Description
The AE2596 series of regulators are monolithic
integrated 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 AE2596 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. Available in a standard
5-lead TO-220 package with several different lead bend
options, and a 5-lead TO-263 surface mount package.
Other features include a guaranteed±4% tolerance
on output voltage under specified input voltage and
output load conditions, and±15% on the oscillator
frequency. External shutdown is included, featuring
typically 80 µA standby current. Selfprotection features
include a two stage frequency reducing current limit for
the output switch and an over temperature shutdown for
complete protection under fault conditions.
