3A Step-Down Voltage Regulator LM2596HV
DESCRIPITION
The /0+9 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 ADJ 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 /0+9 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 /0+9 are
available from several different manufacturers. This feature greatly simplifies the design of
switch-mode power supplies.
Other features include a guaranteed ±4% tolerance on output voltage within specified input
voltages and output load conditions, and ±10% on the oscillator frequency. External
shutdown is included, featuring typically 50 μA standby current. The output switch includes
cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault
conditions.
