UMW R UMW LM2575/LM2575HV 2A Step-Down Voltage Regulator General Description The LM2575 /LM2575HV series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 2A 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. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation†, and a fixed-frequency oscillator. The LM2575 /LM2575HV series operates at a switching frequency of150 kHz thus allowing smaller sized filter compontents 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 a 5-lesd TO-262 surface mount package. A standard series of inductors are available from several different manufacturers optimized for use with the LM2575series. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ± 4% tolerance on output voltage under specified input voltage and output load conditions, and ± 15% on the oscillator frequency. External shutdown is included, featuring typically 80 µA standby cur-rent. 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 conditions. Typical Application Features n 3.3V, 5V, 12V, and adjustable output versions n Adjustable version output voltage range, 1.2V to 37V (57V for HV version) ± 4% max over line and load conditions n Available in TO-220 and TO-263,TO-220B packages n Guaranteed 2A output load current n Input voltage range up to 40V n Requires only 4 external components n Excellent line and load regulation specifications n 150 kHz fixed frequency internal oscillator n TTL shutdown capability n Low power standby mode, IQ typically 80 µA n High efficiency n Uses readily available standard inductors n Thermal shutdown and current limit protection Applications n Simple high-efficiency step-down (buck) regulator n On-card switching regulators n Positive to negative converter Note: †Patent Number 5,382,918.
