The LM2575D2T-3.3R4G from Texas Instruments is a step-down (buck) voltage regulator module optimized to provide a stable 3.3V output from an input supply in the 4.5V to 16V range.

Key Features:

• Fixed 3.3V output voltage
• Up to 4A continuous output current capability
• Narrow 4.5V to 16V input voltage operating range
• 150kHz fixed switching frequency
• TO-263-5 package for ease of use and mounting

Common Applications:

• Distributed power systems for telecom/industrial usage
• Point-of-load regulation requiring up to 4A at 3.3V
• Intermediate bus conversion/regulation for DC power systems

Benefits Include:

• Provides simple solution for generating 3.3V from a varied input
• Enables reliable delivery of up to 4A output current
• Optimized for performance within defined voltage parameters

Well-suited for applications requiring a fixed 3.3V supply delivering up to 4A of current from a 4.5V to 16V source.

In summary, the LM2575D2T-3.3R4G is ideal for applications needing high current 3.3V regulation from a limited input range.
