UMW LM2576/LM2576HV 1.Description The LM2576 series of regulators are monolithic integrated circuits that provide all the active functions for a stepdown (buck) switching regulator, capable of driving 3A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3V, 5V, 12V, 15V,and an adjustable output versions. Requiring a minimum number of external components, these regulators are simple to use and include internal frequency compensation and a fixed-frequency oscillator. The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required. A standard series of inductors optimized for use with the LM2576 are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed ± 4% tolerance on output voltage within specified input voltages and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring 50µA (typical) standby current. The output switch includes cycleby-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Note: The LM2576HV is not produced yet. 2.Features 3.3V, 5V, 12V, 15V, and adjustable output versions Requires only 4 external components Adjustable version output voltage range 52 kHz fixed frequency oscillator 1.23V to 37V (57V for HV version) ±4% max over TTL shutdown capability, low power standby mode line and load conditions High efficiency Guaranteed 3A output current Uses readily available standard inductors Wide input voltage range, 40V up to 60V for HV Thermal shutdown and current limit protection version 3.Applications Simple high-efficiency step-down (buck) regulator On-card switching regulators Efficient pre-regulator for linear regulators Positive to negative converter (Buck-Boost) UTD Semiconductor Co.,Limited www.umw-ic.com Jun.2025 1 of 18 PDF
