         DESCRIPTION

       The LM2596HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjustable output version.

Available in a standard 5-lead TO-220 package and a 5-lead TO-263 surface mount package.

External shutdown is included, featuring typically 30 µA standby current. The output switch includes cycle-bycycle current limiting, as well as thermal shutdown, and protection from output short for full protection under fault conditions.
