The Texas Instruments LM2575S-ADJ/NOPB is a monolithic integrated circuit designed for step-down (buck) switching regulator applications. It is capable of driving a 1A load with excellent line and load regulation. This adjustable version offers an output voltage range from 1.23V to 37V, with a maximum tolerance of ±4% over line and load conditions.
The regulator operates at a fixed frequency of 52kHz, utilizing an internal oscillator. It requires only four external components for operation and features TTL shutdown capability for low power standby mode. The device is designed for high efficiency and uses readily available standard inductors. Protection features include thermal shutdown and current limit protection.
Packaged in a TO-263-5 (DDPAK/TO-263-5) surface mount package, the LM2575S-ADJ/NOPB is suitable for various power management applications. The operating temperature range is -40°C to 125°C (TJ). Standard package quantity is 500 units on tape and reel.
This regulator is part of the SIMPLE SWITCHER family, known for simplifying the design of switching power supplies. Its versatility makes it suitable for a wide range of DC/DC conversion tasks where adjustable output voltage and 1A current capability are required.
