The LM2595 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 1A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, and an adjust-able output version. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation#, and a fixed-frequency oscillator. The LM2595 series operates at a switching frequency of150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regu-lators. Available in a standard 5-lead TO-220 package with several different lead bend options, and a 5-lead TO-263surface mount package. Typically, for output voltages less than 12V, and ambient temperatures less than 50*C, no heat sink is required. A standard series of inductors are available from several dif-ferent manufacturers optimized for use with the LM2595 series. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed +-4% tolerance on out-put voltage under specified input voltage and output load conditions, and +-15% on the oscillator frequency. External shutdown is included, featuring typically 85 uA stand-by current. Self protection features include a two stage frequency reducing current limit for the output switch and an over temperature shutdown for complete protection under fault condi-tions.
