Description
- TO-263-5 package
- for Step Down Power Supply 6V- 60V Step-Down To 5V
GENERAL 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, 5-lead TO-263 surface
mount package and SOP-8 package.
External shutdown is included, featuring typically 30 μA standby current.
The output switch includes cycle-by-cycle current limiting, as well as
thermal shutdown, and protection from output short for full protection
under fault conditions.
