LM2576T-5.0 Buck 5V 3A 40V DC-DC Converters DIP IC TO-220-5
The LM2576T-5.0 is a monolithic switching regulator IC designed for efficient DC-DC step-down (buck) voltage conversion. It provides a fixed 5V output with up to 3A load current, making it suitable for powering microcontrollers, embedded systems, and other digital circuits. The device integrates the main switching regulator functions in a single chip, simplifying power supply design and reducing the number of external components required.
Operating with a wide input voltage range up to 40V, the LM2576 series offers improved efficiency compared to traditional linear regulators. It features internal frequency compensation, a fixed switching frequency oscillator, and built-in protection functions such as thermal shutdown and current limiting. Its TO-220-5 through-hole package allows easy mounting and good heat dissipation, making it widely used in industrial electronics, embedded systems, and power supply modules.
Features:
- Fixed 5V output voltage.
- 3A output current capability.
- Wide input voltage range: 4V to 40V.
- High efficiency up to 77%.
- Requires only four external components.
- 52kHz fixed frequency operation.
- TTL shutdown capability.
- Low power standby mode.
- Thermal shutdown and current limit protection.
