Description:The BL2576 (LM2576) series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (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 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 BL2576 (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 BL2576 (LM2576) are available from several different manufacturers. This feature greatly simplifies the design of switch-mode power supplies. Other features include a guaranteed g4% tolerance on output voltage within specified input voltages and output load conditions, and g10% on the oscillator frequency. External shutdown is included, featuring 50 mA (typical) standby current. The output switch includes cycle-by-cycle current limiting, as well as thermal shutdown for full protection under fault conditions. Applications: - Simple high-efficiency step-down (buck) regulator - Efficient pre-regulator for linear regulators - On-card switching regulators - Positive to negative converter (Buck-Boost)
