LM2576 Step-Down Voltage Regulator IC

The LM2576 is a voltage Regulator IC, it uses the Buck-converter topology to step-down and regulates higher level voltage values to a lower level. It is of non-sync type and can take in an input voltage 40V maximum and source an output current of 3A maximum with a peak efficiency of 90%.

Applications:

• Used in battery circuits since they have high efficiency
• Step-down Linear regulators
• Used in small SMPS circuits
• Can also be used to source negative voltage.

Pin Configuration:

• Switch mode step down voltage regulator
• Output Voltage for fixed voltage regulator: 3.3V, 5V, 12V or 15V
• Output Voltage for Variable type regulator: 1.23V to 37V
• Output Current: Up to 3A
• Maximum Input Voltage:  40V
• In-built Thermal Shutdown and Current Limit Protection
• Internal Oscillator: 52-kHz (Fixed Frequency)
• Available in TO-220 and TO-263 packages
