The Texas Instruments LM2576SX-ADJ/NOPB is a versatile step-down (buck) switching voltage regulator designed for low component count power supplies. It operates with an input voltage range up to 40V and can deliver a continuous output current of 3A. The output voltage is adjustable, ranging from 1.23V to 37V, with a typical quiescent current of 5mA and a switching frequency of 52kHz.
This regulator features voltage mode control and includes over-current protection and an enable function. It is suitable for applications requiring efficient voltage conversion with minimal external components. The device is housed in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package, designed for surface mounting.
Key electrical characteristics include a wide input voltage range, specified 3A output current, and a fixed 52kHz internal oscillator. The LM2576 series is known for its high efficiency and ease of use, requiring only a few external components like inductors and capacitors to create a complete power supply solution.
