The Texas Instruments LM2576S-ADJ/NOPB is a monolithic integrated circuit designed for step-down (buck) DC/DC conversion. It provides all active functions for a 3A step-down regulator with high efficiency and requires minimal external components.
Key electrical specifications include a wide input voltage range up to 40V, a maximum output current of 3A, and a fixed switching frequency of 52kHz. The output voltage is adjustable, ranging from 1.23V up to 37V (or 57V for HV versions), with a maximum tolerance of ±4% over line and load conditions. This regulator is non-synchronous.
Packaged in a surface-mount TO-263-5 (DDPAK/TO-263-5) configuration, the LM2576S-ADJ/NOPB operates within a temperature range of -40°C to 125°C (TJ). Its design emphasizes low component count and ease of use, making it suitable for various power management applications.
This regulator is suitable for applications requiring a stable, adjustable output voltage from a higher input voltage source. Its robust design and high current capability make it a versatile choice for power supply designs.
