LM2576 Datasheet 1a & 3a Miniconverter Switching Regulators

Manufacturer: SEMTECH

Overview: POWER MANAGEMENT.

General 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.
