LM2575SX-15

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575SX-15 is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-efficiency DC-DC conversion. It operates with an input voltage range of 4V to 60V and provides a fixed 15V output at up to 1A current. The device utilizes a buck topology with a typical switching frequency of 52kHz. Packaged in TO-263 (D2PAK-5) for surface mount installation, it supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic controller simplifies design by requiring only external diode, inductor, and capacitor components.
• Fixed operating frequency of 52kHz allows for the use of compact passive components.
• Internal thermal shutdown and current limiting protect against overload conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in distributed power supply systems
• Pre-regulator stages for switching regulators
• Efficient linear regulator replacement

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status via the manufacturer datasheet, as legacy versions may differ. Ensure the supplier source matches Texas Instruments or authorized distributors to guarantee authenticity and traceability.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a fixed 15V output from higher input voltages. The TO-263 package suits designs needing moderate heat dissipation without external heatsinks. Consider the 52kHz frequency for balancing component size and efficiency.
