ماژول رگولاتور DC به DC کاهنده 3 آمپر LM2596S

Description:

The LM2596 regulator is a monolithic integrated circuit ideally suited for the easy and convenient design of a step-down switching regulator (buck converter). It is capable of driving a 3.0 A load with an excellent line and load regulation.

This device is available in an adjustable output version, and it is internally compensated to minimize the number of external components to simplify the power supply design.

The LM2596 operates at a switching frequency of 150 kHz thus

allowing smaller sized filter components than what would be needed with lower frequency switching regulators. Available in a standard 5−lead TO−220 package with several different lead bend options and D2PAK surface-mount package.

The other features include a guaranteed 4% tolerance on output

voltage within specified input voltages and output load conditions, and 15% on the oscillator frequency. External shutdown is included, featuring 80 A (typical) standby current.

Self-protection features include switch cycle−by−cycle current limit for the output switch, as well as thermal shutdown for complete protection under fault conditions.
