LM2596M 150K Hz, 2A PWM Step-Down CD/DC Converter

Description

The LM2596M series pf regulators are monolithic intrated circuit that provides all active

functions for a step-down(buck) switching regulator, capable of driving 2A load with excellent

line and load regulation. These devices are available in fixed output voltages of 3.3V,5V,12V

and an adiustable output version. The LM2596M series operate at a switching frequency of

150K Hz; thus allowing smaller sized filter components than what would be needed with lower

frequency switching regulators. The chips are available in standard 8-lead SOP-8 package.

Other feature include a guaranteed +/-4% to tolerance on output voltage under specified input

voltages and output load conditions. The 150K Hz+/-15% is on the oscillator frequency.

External shutdown is include, featuring 80uA(type) standby current. The output switch includes

cycle-by cycle current limiting, as well as thermal shutdown for full protection under fault

conditions.
