u TO-220 and TO-263 packages
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.
The LM2575/6 series miniconverters include a
switching regulator and compensation network all within
the same package. Just add a choke, catch diode and
two capacitors to obtain an efficient DC-to-DC converter.
The current limit and thermal shutdown features of the
LM2575/6 series fully protect the device against
overstress conditions.
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.
