LM2576-3.3 IC REG BUCK 3.3V 3A TO220-5

The LM2576-3.3 is a monolithic integrated circuit that provides all the active functions for a step-down (buck) switching regulator. Capable of driving a 3A load with excellent line and load regulation, this device is available in a convenient TO220-5 package. Requiring a minimum number of external components, this regulator is simple to use and includes internal frequency compensation and a fixed-frequency oscillator. The LM2576-3.3 series offers a high-efficiency replacement for popular three-terminal linear regulators. Due to its high efficiency, it substantially reduces the size of the heat sink, and in many cases, no heat sink is required. A standard series of inductors optimized for use with the LM2576-3.3 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 under specified input voltage and output load conditions, and ±10% on the oscillator frequency. External shutdown is included, featuring typically 50 μA standby current. Self-protection features include a two-stage frequency reducing current limit for the output switch and an overtemperature shutdown for complete protection under fault conditions. The LM2576-3.3 is a versatile and reliable solution for a wide range of applications, including simple high-efficiency step-down regulators, on-card switching regulators, positive to negative converters, and negative boost converters. Its fixed 3.3V output makes it ideal for powering microcontrollers, digital logic circuits, and other low-voltage components.

The TO220-5 package provides excellent thermal performance, allowing the regulator to operate at high power levels without overheating. Its five leads provide easy access to all the necessary connections, simplifying circuit integration and troubleshooting. Key features of the LM2576-3.3 include high efficiency, low standby current, and built-in protection features. The high efficiency minimizes power losses and reduces heat generation, while the low standby current extends battery life in portable applications. The built-in protection features prevent damage to the regulator and the load in the event of a fault condition. When selecting a switching regulator for a specific application, it's crucial to consider parameters such as output voltage, output current, input voltage range, and efficiency.
