Texas Instruments LM2575SX-3-3 is a 1A SIMPLE SWITCHER® buck converter with a fixed 3.3V output. This monolithic integrated circuit provides all the active functions for a step-down (buck) switching regulator, capable of driving up to 1A load with excellent line and load regulation. The LM2575SX-3-3 operates with a switching frequency of 52kHz, minimizing external component size. It features a 4V to 40V input voltage range and requires minimal external components for operation, making it suitable for power supply designs in industrial automation and consumer electronics. The device is housed in a TO-263 (DDPAK-5) surface-mount package and operates across a temperature range of -40°C to 125°C.
