Today, we will introduce the LM2576S-3.3 Miniconverter Switching Regulators 1A & 3A .

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 cumrent 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.
