LM2596T-ADJ

TEXAS INSTRUMENTS  LM2596T-ADJ  直流-直流开关降压逐步递减稳压器, 可调, 4.5V-40V输入, 1.2V-37V输出, 3A输出, TO-220-5

The is a SIMPLE SWITCHER® low component count Step-down Regulator provides all the active functions for a step-down buck switching regulator, capable of driving a 3A load with excellent line and load regulation. This regulator is available in an adjustable output version and requiring a minimum number of external components, this monolithic integrated circuit voltage regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2596 series operates at a switching frequency of 150kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators. A standard series of inductors are available from several different manufacturers optimized for use with this regulator. This feature greatly simplifies the design of switch-mode power supplies.
