The LM2575-5.0WT is a monolithic integrated circuit from Microchip Technology designed for step-down (buck) switching regulator applications. This fixed 5V output version is capable of driving a 1A load with excellent line and load regulation. It simplifies power supply design by requiring a minimum number of external components and including internal frequency compensation and a fixed-frequency oscillator.
The regulator operates at a fixed 52kHz frequency and offers high efficiency, making it a suitable replacement for linear regulators. It features a wide input voltage range from 4V to 40V and a guaranteed 1A output current. The device includes thermal shutdown and current limit protection for enhanced reliability.
Packaged in a TO-220-5 through-hole configuration, the LM2575-5.0WT is designed for ease of mounting on PCBs. Its features include cycle-by-cycle current limiting and thermal shutdown for protection under fault conditions. The device also offers a low power standby mode with typical current consumption below 200µA.
This buck regulator is suitable for various applications including simple high-efficiency step-down regulators, pre-regulators for linear regulators, and on-card switching regulators. Its design simplifies switch-mode power supply creation.
