The new product, LMR33630, offers reduced BOM cost, higher efficiency, and an 85% reduction in solution size among many other features.

Available in a standard 5-pin TO-220 package with several different lead bend options, and a 5-pin TO-263 surface mount package. The LM2596 series operates at a switching frequency of 150 kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation, and a fixed-frequency oscillator. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version. The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation.
