Product Summary

The LM2575SX-5.0/NOPB is a switching regulator designed for use in buck or buck/ boost regulator applications requiring accurate output voltages over combined variations of line, load and temperature. The LM2575SX-5.0/NOPB greatly simplifies switching power supply design. The LM2575SX-5.0/NOPB has a maximum output current of 1A and the LM2575SX-5.0/NOPB 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 LM2575SX-5.0/NOPB fully protect the device against overstress conditions.
