POWER MANAGEMENT
Description
The LM2575/6 series switching regulators are monolithic
integrated circuits designed for use in “buck” or “buck/
boost” regulator applications requiring accurate output
voltages over combined variations of line, load and
temperature. This unique series greatly simplifies
switching power supply design. The LM2575 has a
maximum output current of 1A and the LM2576 is rated
for 3A.

Features
u
Pin for pin replacement for National’s LM2575/6
u
series
DC-to-DC buck or buck/boost converter requiring
only 4 support components
Fixed or adjustable voltages
Preset output voltages of 3.3V, 5V and 12V
Wide output voltage range, 1.23V to 35V
82% typical efficiency @ 5V out
Wide input voltage range, 4V to 40V
Inhibit/enable control pin
Industrial temperature range

u
u
u
The LM2575/6 series miniconverters include a
u
switching regulator and compensation network all within
u
the same package. Just add a choke, catch diode and
u
two capacitors to obtain an efficient DC-to-DC converter.
u
The current limit and thermal shutdown features of the
LM2575/6 series fully protect the device against
overstress conditions.
Applications

Micro controller power supplies
Medical equipment
Industrial power supplies
Instrumentation power supplies
The LM2575/6 series offers an alternative to popular 3
terminal linear regulators by providing higher efficiency
with reduced heatsink size. In many applications a heat
sink will not be required.
