2596, 3A Voltage Regulator IC : Tutorial 12

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.
The LM2576 series offers a high-efficiency
replacement for popular three-terminal linear
regulators. It substantially reduces the size of the
heat sink, and in some cases no heat sink is
required.
A standard series of inductors optimized for use with
the LM2576 are available from several different
manufacturers. This feature greatly simplifies the
design of switch-mode power supplies.
Other features include a ±4% tolerance on output
voltage within specified input voltages and output
load conditions, and ±10% on the oscillator
frequency. External shutdown is included, featuring
50-μA (typical) standby current. The output switch
includes cycle-by-cycle current limiting, as well as
thermal shutdown for full protection under fault
conditions.

[@Arlemowy]

Can I connect the OUTPUT 2 pin to something other than the coil and diode? To something that will control the connection between the battery and the coil and diode. Depending on the signal on pin 2, something will connect and disconnect the battery from the coil and diode. Will I achieve, for example, 10A with an LM2596t which has a max of 3A

[@saneeshelectronica9293]

it will regulate in the defined range .but maximum current is limited. for examble if u use 18 v 2 amp= 36 w , an du gave 12 vdc current= 36/12 3 a input. such scenario ic will get hot. give maximum input voltage within range. so that heat will be less.
