LM2596SX-ADJ

1. Description

LM2596SX-ADJ regulator is monolithic Integrated circuit that provides all active functions Used in step-down switching regulators, capable of Drive 3A load with excellent line and load regulation. These devices have fixed outputs Voltage is 3.3 V, 5 V, 12 V and adjustable output Version.

Minimum number of external Components, these regulators are easy to use and Including internal frequency compensation and fixed frequency oscillator.

LM2596SX-ADJ works at switching frequency 150 kHz, which allows the use of smaller filters Fewer components than required Frequency switching regulator. can be use on Standard 5-pin TO-220 package with several different

Lead bending option and 5-pin TO-263 surface mount package.

These inductors are aimed at LM2596SX-ADJ. This function greatly simplifies the design of the switching power supply.

Other features include ±4% tolerance of output voltage under specified input voltage and output load Condition, the oscillator frequency is ±15%. Including external shutdown function, typical value is 80μA stand-by current. Self-protection function includes two-level frequency reduction output current limit The switch and thermal shutdown function provide comprehensive protection in the event of a fault.
