LM2596SX-ADJ/NOPB Datasheet PDF - TI

●The LM2596SX-ADJ/NOPB is a SIMPLE SWITCHER® step-down Voltage 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. Requiring a minimum number of external components, this 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 required with lower frequency switching regulators. A standard series of inductor is available from several different manufacturers optimized for use with the LM2596 series. This feature greatly simplifies the design of switch-mode power supplies. Other features include a ±4% tolerance on output voltage under specified input voltage and output load conditions and ±15% on the oscillator frequency. External shutdown is included, featuring typically 80µA standby current.
