SIMPLE SWITCHER POWER CONVERTE
AE2596
AE2596
● 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 80µA standby current. Self-protection features include a two stage
frequency reducing current limit for the output switch and an over temperature shutdown for
complete protection under fault conditions.

(AOQL).
Note5: External components such as the catch diode, inductor, input and output capacitors, and
voltage programming resistors can affect switching regulator system performance.
Note6: The switching frequency is reduced when the second stage current limit is activated.
Note7: No diode, inductor or capacitor connected to output pin.
Note8: Feedback pin removed from output and connected to 0V to force the output transistor switch
ON.
Note9: Feedback pin removed from output and connected to 12V for the 3.3V, 5V, and the ADJ.
version, and 15V for the 12V version, to force the output transistor switch OFF.
Note10: VIN = 36V.
Note11: Junction to ambient thermal resistance (no external heat sink) for the TO-220 package
mounted vertically, with the leads soldered to a printed circuit board with (1 oz.)copper area
of approximately 1 in2.
