Onsemi (LM2576T-ADJG) DC-DC Switching Buck (Step Down) Regulator

DC-DC Switching Buck (Step Down) Regulator, Adj., 7V-40Vin, 1.23V-37V/3A out, 52 kHz, TO-220-5 Product Overview The LM2576T-ADJG is a step-down Switching Regulator, monolithic integrated circuit is ideally suited for easy and convenient design of a step-down switching regulator (buck converter). All circuits of this series are capable of driving a 3.0A load with excellent line and load regulation. This regulator was designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2576 are offered by several different inductor manufacturers. Since the LM2576 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. In many cases, the power dissipated is so low that no heat sink is required or its size could be reduced dramatically. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. Wide input voltage range Requires only 4 external components TTL shutdown capability and low power standby mode High efficiency Uses readily available standard inductors Thermal shutdown and current limit protection Moisture sensitivity level (MSL) equals 1 Applications Power Management, Industrial Product Information Topology: Buck (Step Down) Input Voltage Min: 7V Input Voltage Max: 40V No. of Outputs: 1Outputs DC / DC Converter IC Case: TO-220 No. of Pins: 5Pins Output Current: 3A Output Voltage Min: 1.23V Output Voltage Max: 37V Switching Frequency: 52kHz Operating Temperature Max: 125°C Product Range: LM2576 MSL: MSL 1 - Unlimited
