LM2575T-5G

The LM2575T-5G is a step-down Switching Regulator ideally suited for easy and convenient design of a step-down switching regulator (buck converter). It is designed to minimize the number of external components to simplify the power supply design. Standard series of inductors optimized for use with the LM2575 are offered by several different inductor manufacturers. Since the LM2575 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 by the LM2575 regulator is so low, that no heat sink is required or its size could be reduced dramatically. The LM2575 features include a guaranteed ±4% tolerance on output voltage within specified input voltages and output load conditions and ±10% on the oscillator frequency. External shutdown is included, featuring 80A typical standby current.
